I am looking to buy a macbook air base model by this weekend ( friday i hope ). I saw one for $ 999 plus tax ( refurbished, apple online store ). I think that`s a pretty good deal but am i going to have the same problems ( core shutdowns, video paroblems, all related to heat). Or should i wait for the Rev B versions to arrive at the online refurbished store. I know price is not going to be same, and money is always a factor especially in this climate. I will be using it for basic tasks ( internet, msn, slingbox,iwork,itunes and mail app.) I have a new unibody macbook top model with 4gig ram ( my main machine ) which is connected to apple 24 inch display. So what i should i do guys???
