My ideal IDE should need a whole datacenter and use AI to help me work better.
If your IDE isn't using your whole hardware, it's probably not doing enough.
Some IDE's are just better at doing similar things than others. VS2k10 intellisense is orders of magnitude faster/stable/* than implementations in other IDE's.
Have you tried emacs? ;)
In all seriousness though, I do agree with this with the exception that the IDE needs to make room for the application you're writing. If it can use an extra core to provide smarter autocompletion or discover potential bugs, I'm all for it.
I agree completely but I use most of the popular ones so I'm starting to suspect what I really need is a better IDE!
