Hello guys and girls, I would appreciate it if you could give me your advice on this: Should I or should I NOT buy a 27'' i5 iMac now? Put otherwise, is it more reasonable to wait for Rev B? If so, how long usually before Rev B is out? I am in the market for a new desktop computer and I would like to have it ASAP. Nevertheless, I can still wait if I must since I have a MB to work on for the time being. I have started to have doubts about buying now once I have found out about the problems pestering Rev A 27'' iMacs: - cracked screens (only on i7s? - flickering screens - Flash issues What is your opinion? And, what is your experience with your brand new i5? Thank you very much!
