Yesterday Apple revealed the new iPad. You can read all about it elsewhere or go right to the source if you want to buy one.

As usual the announcement was preceded by feverish speculation. Would the new device come with iOS 6? Was it going to allow users to ‘touch’ pixels (or tixels) through advanced haptic feedback technology? And what about Siri?

The answer to all these questions turned out to be “no”, but some new features did make it in. First and foremost was the Retina display, which doubles the screen resolution. It’s easy to underestimate the importance of this – talk about display resolution never really captivates ‘normal’ people – but it does matter.

The other enhancements possibly fall into the “so what” category. Take the support for 4G and LTE connections. If you’re in the UK you might well ask, support for what? These are new standards for mobile networks that are becoming common in north America, but they’re still some way off here. So that enhancement isn’t really relevant to British users.

And then there’s the new quad-core processor. The less said about that the better. It’s not that it isn’t important – it’s just that it really doesn’t excite consumers. Remember in the early 2000s when Windows devotees would mock the lower clock speeds of PowerPC CPUs, believing this proved the inferiority of Apple machines? You probably don’t: it turned out that no-one cared. Apple refused to join a CPU arms race and it turns out that they were right.

So this leaves Apple with a new product announcement that is evolutionary rather than evolutionary. No freaky futuristic stuff, no “one more thing”. But does it matter?

I don’t think it matters at all really. The iPad dominates the tablet market and there’s nothing on the immediate horizon that’s going to change that. When Windows 8 launches it’ll be in a battle against Android for second place, but that could end up being a pretty small prize to fight for. There’s a more tangible threat to the iPad from the Kindle Fire but Amazon has work to do if it’s going to convince people that these products belong in the same device category. Apple’s dominance of the tablet market is ensured for the foreseeable future.

Given all this, throwing new features at the dominant product in an attempt to revolutionise it would be a bad move. When you’re behind, the “hail mary pass” – a single recklessly ambitious scheme to stave off disaster – is a good strategy. But when you’re ahead that’s the last thing you want to do. It’s what Microsoft did with Vista, and it ended up spending millions giving the world a product it didn’t need. Apple isn’t going to be “doing a Vista” with the iPad any time soon.

Since the launch of the iPad, hubris and hysteria among technology commentators has been gradually increasing. The device is the future; Rupert Murdoch thinks it’s the saviour of journalism; it will change the world; it “can replace any real-world object you own”.

One notion that I take exception to, however, is that the iPad signals the death of the keyboard and that touch interfaces are destined for ubiquity.

Now, I’m no technological conservative – I’ve been using touch-screen phones since before the iPhone came out. But I think a more fundamental point is being missed here, which is that the roles computers play in our lives are multiplying greatly.

Computers used to play a relatively limited set of roles which could be supported with a common set of interface models, mainly centred around the keyboard and the mouse. The keyboard & mouse setup worked when the computer operator was sat at a desk, had enter lots of data from a large character set, and needed direct access to many (maybe even several hundred) on-screen controls offered by their applications.

Today, not every computer user is sat at a desk and in the need state described above. Computer users might be on the other end of a phone line from the machine itself, operating it through a (notoriously infuriating) voice interface. They might be delivering a parcel and collecting the recipient’s signature using a handheld computer’s (notoriously infuriating) pen interface. And of course the computer user might be using a personal device like a smartphone, which needs to be small and light and whose functions don’t require the sort of  intricate and precise interactions supported by the keyboard/mouse combo.

But this doesn’t change the fact that some computer users will still be in situations where the keyboard and mouse paradigm is appropriate. Therefore the keyboard will not die.

What things like the iPad illustrate is that we are using computers more than we used to – in a wider number of contexts and for a wider range of reasons. They don’t replace what we already have, they’re just a new addition to our collection of tools.
