> The places where my hands interact with the machine are much more efficient and pleasing on a mac

In general I'll agree with you but there is ONE thing that I don't like on Macs and still exists to this day (I believe). The notch in the aluminum below the trackpad to make it easy to open the machine has sharp left and right right angles, and that pokes me from time to time.

I figure that's one of those 'this looks better' things, but it wasn't a problem on the older machines that had physical latches and a button to open the lid.
