No thanks!
I think the trackpad idea would be a big mistake! I certainly would not buy it. what a pain in the rear to dial, text msg, or pretty much anything for that matter. I have several macs including the MB i'm typing on now and have been an avid Apple afficianado for many, many years, and I cant imagine that they would put out such a poorly thought out design. I think it would be clumsier than my Treo650 which, if they do it right, I would dump in a second for an Apple product. It has to be as cool and easy to use as an iPod!
