I would appreciate some advice on buying an imac. I live in the UK, if I were to buy at the moment I would buy the i7 processor with the 2gb video card. Reading this forum I understand that Apple are due to upgrade this model in the near future. The question is simple, do I buy now or wait (which is difficult as I want my hands on a Apple sooooo Muchhhhhh) for the new model. Is there a track record for Apple to release new products if so what is it and also what is the likley sepc of the new imac? many regards
