So i want next month or so to buy an 21.5" imac (2.9Ghz, fusion drive,650m geforce). I think i will keep this at least 3-4 years.So i read all over the place, only here on this forum at least a dozen of people who complain about this new machine, and attention in the manufacturing of apple products began early with the iphone 5. My question is...this issues will be there still after 1-2 months ?
