In my view, that's like the perfect travel laptop--it's light, thin, absolutely stunning screen, and very easily portable.

However, as they say, old habits die hard and though I came of age as a Mac person, my long ago Corp days introduced me to the IBM, now Lenovo, Thinkpads and I've found their keyboard to be the best of any laptop I've ever used. When I anticipate needing to type a bunch, which happens from time to time, I picked up an X Series as a compromise between the keyboard I prefer and light weight form factor.

Now, if Apple could produce the current Air with an Thinkpad keyboard, it'd be my perfect laptop.
