Opposite for me. I like Gimp and I hate Photoshop.

I really dislike the way software has to be acquired and maintained in Windows. And there are so many barrierrs to doing things. I didn't realize it until I removed myself from that system for long enough to get used to a different way.

I love the repository approach of the major Linux distros because it is like having an app store (get almost anything and everything in a consistent way from one friendly place) where everything I need is free.
