have you tried the Gimp? it is similar to photoshop. I use it for family albums and such.
I’m more concerned about my audio stuff.
Proaudio digital audio interfaces (expen$ive soundcards to the layman) need special drivers and very few if any support linux.
And there is very limited audio software on Linux.
There is a host or two, but almost zero VST plugin support, so it is just impossible.
And ther is no way I could run a Windows virtual machine on top of Linux, because I need ultra low latency and no excess processor overhead.
I’m already running a quadcore i7 and 6gb of RAM in Windows 7 x64, and I could always use more power!
