Having gone to the trouble of making that long blog post about productivity tools in Windows for Web Developers, I went and switched to Ubuntu on my main desktop PC and I'm now wondering if I'll ever want to use Windows again. I'll briefly mention a few things about my Ubuntu experience so far that have really impressed me.

1) It's unbelievably easy to access and install new free software.

2) Unlimited desktop panels (really really useful)

3) Total control and configurability without the agony of trying to modify your Windows experience

4) gEdit (I know I JUST said I'd probably never switch from Notepad, but...)
