I just wanted to say that I have absolutely no regrets. Before I was using Aptana, but it lacked the subversion support, so I made the switch and it was a great move. The ability to move between projects, seamlessly, and commit updates from with the ide is amazing.
The only thing I would change, is the ability to split the view to side by side, as opposed to over and under.
Well done to the guys at ActiveState. Great product
