Posting this from my six month old Macbook Pro 15" on which the spacebar has just started doing double spaces. Going to try and clean it with compressed air, but even if that works, it's unacceptable in my opinion that such a key piece of hardware on such an expensive machine should be so fragile.

The fact that at some point I'll have to take it back to Apple and probably be without it for several days due to the complexity of the repair makes this 10x worse - I am freelance so need this machine for work, so being without it (especially for such a seemingly trivial reason) is unacceptable and absolutely not what I expect when I buy Apple (previous Macbooks have worked for years without a single issue).

If they release a redesign, I'd swap it in a flash (I do actually quite like the keyboard to type on otherwise, but seems like the quest for thinness has gone too far this time!), but if this problem is as widespread as it seems who knows what it will do to resale values.

Would be great to get talk of this spreading as far and wide as possible, as judging by anecdata on Twitter and elsewhere, I am far from the only one with these kind of issues, and to me that implies a fairly major design flaw.
