I wouldn't buy the first version of any apple computer. Time after time, apple releases a new model before the holidays, and then releases newer models the next month with better specifications at the same price. That is when to buy.
Nonsense. Apple never releases a new model one month and then another new replacement model the next month. Updates are at least around six months apart.
UNLESS you mean that they release "fixed" models a month later, in which case that happens with anything new. The first version ALWAYS has a few bugs - be it computers, software, cars, TVs, etc., etc.
