I have either adapted to it by placing the heels of my hands fully onto the palmrests, or just use my laptop differently than most because i have never really had a problem with my MacBook edge.
I can not think of any products off hand that do what you want, but perhaps someone else can.
This is why I am about to buy a MBP. I cannot use the macbook for extended periods of time... And the keyboard is too low to be holding your wrists up in the air for more than 5 minutes.
I've been typing a lot on a colleague's Macbook lately, and initially I encountered the problem of the wrist slicing edges and was flabbergasted that Apple would make such a poor design.
The best way to get around it seems to be pushing it to the far edge of the desk/table so that you have as much tabletop in between you and the Macbook as possible to rest/prop up your arms on.
I noticed this the last time I was in an Apple store. The edges are really sharp compared to the edges on my iBook. They definitely aren't comfortable to rest skin on.
this is probably one of my biggest gripes with my MB. Also the weak-feeling hinges. I feel like i'm very slowly committing suicide. As one poster said, the keys aren't deep enough to allow for "correct" hand posture. Typing "correctly causes finger strain with such a shallow key depth.
I have never complained about an Apple product before this post, but damn, the edges really are sharp. My forearms get really marked up and sore after using my MB for a while.
I know I should change the position of my computer but this is the way I have been using a laptop for years and I am comfortable this way (except, of course, with the MB )
Another kind of weird thing is that the fonts don't really look smooth on the MB like they did on my powerbook 12". Small text is hard to read. weird. On my PB, everything was so crisp and clean, even really tiny fonts.
I think that some macbook's edges are sharp while others not so much. Mine are very sharp and it's the reason I'll probably upgrade when these new aluminum MacBooks hopefully come out. I just hope the design feels as good to me as the 12" powerbook did
I would but its 85º out right now. My forearms are really sore. This computer will be going back to the Apple Store tomorrow. I can't take it anymore, its annoying and painful.
Just sit the MacBook at a different angle, that's what I do. My wrists set fully on the wrist rests, but don't hang off the edge (or else don't touch at all, which is better for me but more tiring). Just a strip of tape or something over the edge would probably help too, though I'm unwilling to mar the appearance of my computer for that.
