I find this truly idiotic. I am not averse to change, and if this is some kind of tablet--then ok, they have their uses for certain people. But a laptop without a keyboard is just not an advance in technology that's actually useful for people.
Sometimes technology doesn't give the consumer any benefit, and a touch keyboard is just that, a useless feature developed for marketing purposes to make people think it's some great tech advance they have to have when they really don't.
Then you have clearly not used a multi-touch pad yet. Once you use a new MBA or MBP (with the multi touch pad) you won't be able to go back. Simple internet use is a MILLION times better than having to drag your finger to the back button, two-finger scrolling is a dream, I could go on.
You don't honestly think we'll be using a mouse and keyboard over the next 10 years do you? You can hate on it all day, but the truth is it will "fail" as much as the iPod "failed". At first it's very cool and weird, soon it becomes commonplace.
