Have a new MB that just came today. I am new to Apple (or back to apple after 15 years with PC's). *Love* my iPhone and felt the express urge/need to develop for it using SDK. ;-)
I have to say the edge is ridiculous. I'm shocked, really. Those of you who want to downplay it should realize it is an issue and there's enough people talking about it... Considering apple's small market share in notebooks and consider how many people would even bother finding a forum to post about this, I'd guess it's a serious problem.
To echo what others have said, it's not so much with typing -- more when I move my hands down to more casually scroll around with the track pad. Love multi-touch - hate the chafing.
I've been talking about my excitement for this MacBook for weeks. The first one was on the Fedex flight that crashed in Japan, so I've had time to chirp about it coming in. ;-)
Unfortunately, the edge is definitely enough for me to tell people they really need to think long and hard before they get one of these. *shrug* (As it sits next to my bevel edged Dell XPS M1210).
