Hello, I've just sold my pc and I'm looking to buy an imac. I'm a student, so I can only afford to buy the basic 21.5" with the 3.06ghz i3 processor. I have heard great things about the i5 and i7, but nothing about the i3! How is it for performance, and how does it compare to the older core 2 duo or the new i5? Secondly, I hear lots of talk about an imac refresh in the next several months with a new screen size and lower price point. I'm guessing a lower price means that the technology/performance won't be a huge advance from the one I'm looking to buy now? I can't really wait to buy the new one as my studies start up again in two days time, so I'm really just looking for reassurance that it's OK to buy now! Many thanks & best wishes for 2011!
