Why the iPad doesn't need a USB port…


There’s been much speculation in the media over the last couple of weeks about the iPad 2, reportedly due for release early in 2011.  Two of the many rumours I agree with – 2 cameras and retina display – because they are already present in the iPhone 4 and latest iPod Touch.  HD video recording is also a real possibility in the next generation of iPads because again, this ability already exists in the aforementioned iDevices.  Talk of the iPad 2 having a USB port however is leading people down the wrong path, IMHO.

The iPad doesn’t need a USB port.  The camera connection kit that already exists as an accessory provides a USB connection with your camera, but only that – your camera.  You can’t plugin a memory stick as the iPad’s operating system (OS) only recognises signals from a camera; the ‘universal’ part of USB doesn’t apply to the iPad like it does to your laptop.  Instead, if you try and access data on a pen drive, you’re presented with the following error message:

So unless you’re transferring photos from a camera, the kit’s USB connector is a no-go zone.

The iPad doesn’t need a USB port.  The other connector in the current camera connection kit supports SD cards.  Great you say, but again, like the USB connector, this is inextricably linked to the iPad’s camera roll, so it’s another example of only being able to transfer photos. I like the SD connector though as it means no cables are needed (I don’t even use cables when transferring photos to a laptop – haven’t done so in several years! – always use the SD slot instead).  When the iPad’s OS registers the SD card, the camera roll opens and you can download any or all of the photos that you wish.

Too bad if your camera uses compact flash though…

The iPad doesn’t need a USB port.  There are already heaps of apps, paid and free, that allow you to transfer photos between iPhone, iPod, iPad and computer.  Some of these focus on transfer between iDevices only, some are just Mac and others support PC as well.  Some use WiFi whilst others use Bluetooth.  The point is, it’s already possible to transfer photos between different devices using apps AND wirelessly.  What then, does a USB port offer users, really?

The iPad doesn’t need a USB port – and this is the clincher!  The iPad uses the iPhone OS.  Given the nature of the OS it’s easy to identify that the iPad is NOT a full replacement for a laptop or desktop – not yet, anyway.  Don’t get me wrong, I absolutely LOVE my iPad (and will likely be first in line for iPad 2), but I’ve found that the iPad’s biggest area of weakness is related to file management. I lot of people seem to assume that the iPad can be a replacement for a laptop, but don’t understand the implications of the menu-based OS that controls how users interact with the hardware and application software.

The iPad doesn’t need a USB port because the OS dictates that all file management is app-based only.  Sure, you can import and export Word documents etc to and from apps, although I’ve found this to have a high failure rate.  Developers have made some improvements, but there’s still much work to be done in this respect.  The ‘open in…’ feature seen in Safari even doesn’t respond particularly well to Apple’s own Pages app.  I’ve lost track of how many times I’ve tried to view a document from the Internet in Pages, Goodreader, ReaddleDocs and many other (generally good) productivity tools only to have it fail.  It works about 10% of the time, which quite frankly is unacceptable.  The iPad’s OS doesn’t have a My Documents/Library (PC) or Finder (Mac) component built into it, unlike the operating systems we’re familiar with on our computers.

Seeing a quick view of a document in Safari works, but trying to download this document into another app is a different ball game and one in which is the most frustrating thing about the iPad.  I’ve had students wanting to download documents from their Blackboard courses onto their iPad, only to discover that they can only ‘view’ the file, not ‘download’ it. Even Pages doesn’t allow you to organise documents into folders.  If you’ve only got a limited number of files then fine, but imagine being a student trying to organise potentially hundreds of files across all of your courses in even one academic year.  How many files do you have on your laptop or desktop right now?  How do you organise these files? Could you replicate that file/folder structure in the iPad?  If you’re a student or teacher, my answer to that would be probably not.

The iPad doesn’t need a USB port because the OS precludes it’s use.  Wireless technologies mean users can transfer photos and files (sometimes!) from one iPad to another (or iDevice), or from computer to iPad. I have so many productivity apps on my iPad that it’s a bit embarrassing to count them all!  Yet I haven’t found the one killer app, mainly because whilst each have advantages, they all seem to fall down in how they manage files (documents such as PDF, Word, PPT or equivalents etc, not photos) and/or in what type of files they allow users to transfer (especially without having to use iTunes, which is bloated and horrid on a PC!)   There’s no coincidence that it’s photos that seem to be the easiest to transfer rather than documents.  That’s because at the end of the day the iPad, being a consumer device, was designed for media rather than file management.  There’s much potential in this hardware, but there’s still some way to go before we all ditch laptops and desktops in favour of a slate – teachers, students and businesses alike. And until we get to that point, there’s really no clear reason why the iPad needs a USB port at all.

Images from iPad OS 4.2 (beta)


Ok, so finally getting around to adding images related to my previous post about the new iPad operating system – this is the bit I can’t do using the iPad itself! So…back to the laptop.

Multi-tasking

This is the view you get when you tap the Home button twice.

The lighter icons in the top row are on the task bar of the Home screen.  The coloured icons are the 5 that I had running at the time the shot was taken: Kindle for iPad, Angry Birds, Twitter, Photogene and Safari, in this case.

Click the lighter section of the screen to exit the multi-tasking view.

Different wallpapers

As you can see, you have the choice of different wallpapers.  I don’t think this really adds anything to how you use the device, but it does give you options.  The iPhone 4 does the same thing.

Folders

As mentioned in the previous post, you can now arrange your apps into folders.  The iPad allows for a maximum of 20 apps in one folder.  You can also rename the folders to whatever you like.  The default folder names given by the OS matches the category of the initial app that you put in the folder (i.e. category from the App Store).

Using 4.2 beta OS on the iPad


//

I’ve been using a beta version of the next iPad operating system – version 4.2 – for about seven weeks now. So how is 4.2 different to the iPad’s original operating system? Four aspects immediately spring to mind:

Multi-tasking
It’s now possible to run more than one app at a time. It does this in the same way as OS 4.1 on the iPhone 4, not like Mac OS X or Windows does (i.e. multiple forms). You’re still restricted to the menu-based interface, but currently running apps can be easily accessed by double-clicking the Home button. The 4.2 upgrade is more about adding functionality rather than aesthetics.

I haven’t noticed that this has an undue effect on the battery life, but one would think there is some impact. I’m in the habit of closing apps that I’m definitely not intending to use in my current session. To do this hold your finger down on one of the apps in the multi-tasking section and click the top left-hand corner of the apps you want to close when the red/white crosses appear.

The iPad supports six app icons across the width of the screen. So what happens if you have more than six apps running? Just swipe your finger from right to left to see the other icons.

Locking the screen orientation
The previous iPad operating system (3.2 from memory? The OS that came with the iPad when purchased) used a button in the top right-hand side of the device to lock the screen orientation – I wish the iPhone had this feature! In 4.2 this is now accessed through the software itself.

Double-click the Home button to enter the multi-tasking view. Swipe your finger from left to right. The ‘lock screen orientation’ button is on the far right. There’s also a button to quickly access music and adjust the screen brightness.

Wallpapers
Like the iPhone 4, you can have two different wallpapers; one as the home screen and a different wallpaper for the lock screen. You can have the same wallpaper for both the home and the lock screens too, if you wish.

Folders
Another feature that 4.2 has in common with 4.1 OS on the iPhone is the ability to group icons into folders. It’s possible to have up to 20 apps stored in one folder (the iPhone stores slightly less due to limitations posed by the screen size.) Rename folders to suit your purposes as well.

It seems like an innocuous feature, but it makes a huge difference when you can create some sense of organisation with your apps AND not have to flick through many screens – it’s possible to cut this last aspect down to two or three screens, yet still have hundreds of apps on the device.

What’s not quite right with 4.2….?
The only issue I’ve experienced with the beta is that some apps don’t work. An app may initially load, but then quit as soon as you try and use it, or an app will refuse to load at all. In this case the screen may just flash before returning to your screen of icons.

Surprisingly though, I’ve found most apps to work fine under 4.2, including apps that I’d (inadvertently) transferred from my iPhone to iPad (I reeeaaalllly DON’T like iTunes…)

Developers recognise that some apps may have problems with 4.2 though and updates to their software contain fixes. I now have apps that didn’t run on 4.2 when I first upgraded the OS, but now they do.

Now if I could just get WordPress and Safari to work in harmony on the iPad, I’d be sweet. I’ve typed this post on my iPad (admittedly with a wireless keyboard), but can not get images uploaded. Hmmm…may try my laptop later…
