i got the mba the first day it came out.then i had it exchanged a month later due to core shutdown issues. it was great but it would get slow when watching videos after a long time and i use vw fusion with xp and it would just get slow so i decided to sell it and now i have the mbp and i love it but it is so BIG!!! i dont know what to do should i return it for a mba again? or should i keep it. i like how i could carry the mba everywhere it was so portable and the mbp is not. what should i do. any ideas?
