I haven't really looked at anything since XII... I do mostly development, and my image work is mostly relegated to slight color shifting and/or cropping/scaling. I do wish Paint.Net were a better cross platform option... I've used Pinta, but it's been kind of buggy and isn't nearly as well flushed out.

It's a shame that so many tried to re-bundle Paint.net in sleazy ways... though the ads on their own site are horrible, and I don't fault the main dev(s). I just would love to see Pinta or anything else become as easy to use. I may try to dig up PSP7 and see if I can find a key for it.
