MacBook Touch Years Away

Touchscreen Macs are in the news today. Forbes.com has written about the possibility of the computer being 3 to 5 years away.

I'm not sure how I feel about that idea. I think it might be hard to give up scooting my finger along the touch pad. I have many questions about what a touchscreen Mac might look like. My guess is that it probably will be like a tablet computer offered by the PC makers.

Why hasn't Apple introduced such a machine already?  I don't know the answer to that, but there's much speculation at Gizmodo as to why it hasn't and what it might look like when it finally does.
