Late next year if the Mac mini survives.SO, it looks unlikely we will see a new mac mini in January, However, do you think it will swap over to 45nm straight away?
You can't upgrade the processor. The processor on this unit is soldered on the main MLB...it wouldn't be worth it to invest in a new MLB and Processor to upgrade it. Who knows what kind of firmware issues you would have. Cheaper to just buy a new one.
