This is the most elegant critique to the current line of Macs I've read so far. I hope it reaches the right eyes and ears.
I tried a 12" MacBook. It was a gorgeous machine and wildly fast given its size.
But its trackpad is a grotesque monstrosity, and while I writing I too often activated it by accident, flinging the cursor to some distant spot by accident. Then I'd have to stop, recover, and reset.
I can't figure out what usability case would mandate a trackpad that large.
I returned the computer and suspect that the last generation of 13" MBPs may become "legendary," because they don't make the ginormous trackpad error.
