I disagree.First, you sound like a troll.
Wow. This is why people bash Apple fanboys.
I am currently typing on a white MacBook that is on its second battery because of this exact issue. The funny thing is, my old battery still gets ~2 hours of battery life, but it is ridiculously bulged out. This was a known problem with a previous Apple computer and the OP just wants to know if the MBA suffers from the same problem. I would also be interested as I am considering a MBA for my next computer.
This. I've never heard of it happening commonly outside of the old multibody MBP's.
If one reads the OP's post, it asks one simple question without any accusations or trashing of Apple.
Perhaps you have a deep seated need to be negative and accuse. Why not respond without assuming, or accusing. It makes one look better when they are friendly.
How common is it...
But in the gripe department, does anyone else find the paint on the MB-A to be kind of glittery and 1990's in a bad way.
If anyone from Apple is reading this thread (and I know you probably are) possibly consider a matte finnish for the next revision.
Just a suggestion.
