You just KNOW that's the future of Apple keyboards.
A sad, sad future lies ahead...
And it's a bad thing that we may have access to an additional form of input?
I think we're jumping to conclusions about the bleak future of keyboards here... not you necessarily Kishy... I mean a lot of folks in general.
About an hour ago I had to crunch some numbers on my MacBookPro. It took longer than usual because I'm used to having a 10-key. I kept hitting the wrong buttons. Now, if I had that ASUS keyboard/netbook with the small touchscreen at my disposal, I'd have access to a 10-key interface when I needed it. The keyboard doesn't have to go away. It's not an either or proposition.
MacBookPros have big open areas next to the glass trackpad and below the keyboard. It's enough space to have a ten-key, though for obvious reasons a real ten-key would be highly impractical there, but a virtual ten-key would be a huge convenience. It wouldn't exactly be the same as having the real thing, but it'd sure beat trying to peck my way through some accounting without a number pad.
Of course, mobile devices force a tradeoff to give you their portability. Improvements in technology have greatly closed the performance penalty, but nothing will ever change problems created by basic physics. You can't stuff a 52" Screen onto a 15" block of metal.
With laptops becoming more and more powerful and more and more people using them as their primary computer, there's increasing demand for more fully featured laptops and one of the things that power users need is more buttons. Where do you put them?
I seriously seriously doubt that Apple is alone in pursing this kind of thing. It is such a no-brainer approach to a common physical constraint of shrinking electronics. The only reason we're talking about this as an Apple effort is because they live under a bigger microscope these days.
Just look at the ASUS keyboard with a screen. Someone else already thought of it and got to market with a live product. It's not exactly the same thing as what the linked article describes, but it's the same type of idea.
