It would be good to know:
1) What is the first thing - component / problem that users will report when using the iMac 20". I have just bought one and cant fault it.
2) How the iMac will get better over time?
For me the iMac is already pretty powerful when you take into account bus speed, CPU. What improvements will Apple make in the near future and when will these be expected.
3) When will the next new shape iMac be released. Im not talking about faster - im talking about a completely new design.
This thread should get interesting.
