Surely by now there's can't be anybody on earth left that hasn't heard of the iPad? We're going to assume that you know pretty much all about it by now, so this test won't really about the iPad itself, but the iPad on a 3G network in the UK.

First of all, forget anybody who tells you the iPad is just a 'giant iPhone', because it's an idiotic statement that misses the point. The iPad is a rethinking of what a computer-based device is for, and how we go about performing computing tasks. The key here is what Steve Jobs said "[the iPad] has to be far better at some key tasks ... browsing the web ... email ... photographs, watching videos, playing games".

It's important to note that the iPad is not designed to, nor is it capable of, completely replacing your desktop or laptop computer. Not least of which because – like the iPhone or iPod touch – the first thing you need to do is connect it to a computer and fire up iTunes to activate, setup, and sync the iPad with your media collection. You will also need to use iTunes to update the system software and restore the iPad should any problems arise. So you still need a computer.

People who bemoan (and weirdly there seem to be plenty of them) the lack of this, or that, function on the iPad (whether it be SD Card slots, USB Ports, Adobe Flash support) are also missing the point. The iPad is better than a laptop at those key tasks because it lacks other features. It lacks the clutter of Mac OS X, the keyboard, the mouse, the hardware sockets and above all the unused applications, utilities and system preferences that cram a modern operating system and steal parts of your life moment by moment as you spend time fixing things, rather than doing things.

iPad and accessoriesBy ejecting much of the clutter, Apple has enabled both the device, and you, to focus on what it does well, those key tasks that Steve Jobs talked about. And like the proverbial girl from the nursery rhyme, when it's good it's very, very good.

Surfing the web on an iPad is an absolute joy, as is watching videos, sharing photographs, and all those "key tasks" that Steve Jobs talked about. And of course, there's Apple famous App Store with thousands of great apps. As you'd imagine some make more of the iPad's large screen estate than others, but the ones that do (such as The Elements, The Guardian EyeWitness, and Magic Piano, and so on) each offer a fantastic, and in some cases completely unique, experience.

The display, the same type of high-quality LED display found on iMacs and MacBooks deserves special mention. The vibrancy and quality produced by this piece of hardware is superb.

There are some technical innovations above and beyond the iPhone. The multitouch display can handle up to all 10 fingers at once (tested with Pianist Pro) and the A4 processor is a vast improvement on the chip in the iPhone 3GS, both in terms of actual speed and energy performance. Battery life deserves a mention all of its own – being measured in days rather than hours. We tested the iPad extensively and got 11 hours and 15 minutes from pure video playback. We tested audio playback and after 43 hours of constant playing (and still having 71 per cent of the battery left) he abandoned the test. In regular usage we find ourselves having to charge it up every three or four days.

That's not to say that the iPad is perfect. This is still a first-gen product and we can certainly think of ways to improve it. Some form of multitasking, due later in the year, will be welcome, as would the ability to run multiple user accounts. We're sure that software updates will introduce these, and other, new features over the next few years.

There are also things that we'd like to see in the hardware: a built in SD-Card reader and the FaceTime camera from the iPhone 4 are both likely to be included in future iterations.

Apple iPad 3GAnd, of course, it's clearly less capable than a MacBook in many ways. Sooner or later you will attempt to do something, upload images to an online website for example, and find that this a task the iPad simply can't do (in this case because the image uploader is most likely designed to integrate with files from a Desktop, not the Photo app in an iPad).

But consider some of other things it lacks: viruses, malware, complex installation processes, software errors, backup requirements, complicated network setup... the list of all the tedious computing requirements that form part of daily life that have been yanked out of the iPad makes it completely refreshing. Let's put it this way: every bank should be getting its customers away from online banking and towards iPad and iPhone apps as soon as possible.

Ultimately, the iPad is a device that is superb for consuming content, but not as good as a Mac for creating it. The experience of reading a book, graphic novel or – increasingly – a virtual newspaper, or watching a video, showing off photographs, or just flicking around the web and checking your email is an utter joy. We can't overstate how great it is to do all these things on a handheld touchscreen device with a big LED display.
