They have a small error in their intellisense demo ;)
The downside with all these kind of products is that they slow down the IDE if your project gets bigger and bigger and for example you have complicated forms with a lot of eventhandlers (and thus a couple of 1000 lines of code.).
VS.NET 2005 is already slow on my Xeon 3Gz box if I type code at line 3000 or so in my large interfaces.cs file and I fear that having these kind of tools running inside the IDE as well will not make it any quicker. So the real test would be: how does it hold up in a large scale app with several projects and hundreds of thousands of lines of code.
flipdoubt: I have my reservations about CodeRush, but mainly I'd rather have reshaper due to the real time compilation and refactoring and navigational support.
I suppose I should do a full review of CodeRush one of these days..
Roy, if you do, pelase don't forget to include Refactor! pro, the combo is quite nice. One of the best features of this combo is that it doesn't bring down VS.net with an outofmemory exception, whereas VS+Resharper quite often does (with large solutions (15+ projects) and rediculously large files (6000+ lines)).
