Photoshop runs great under Wine. And for the price tag (free as opposed to $700) Gimp offers a LOT of features that Photoshop does (I absolutely LOVE Photoshop BTW) and all it really requires is a bit of a learning curve. Sure, professionals will use Photoshop, but for the average home person who cannot afford to shell out $700 for a piece of software, the Gimp is a very admirable alternative.

Get a bittorrent client, tap in "Photoshop" and roll. Just as free as Gimp.
Learning curves don't interest me, it's the eternal excuse for all that stuff. Productivity is the king. Money needs to be made (if you're not a hippie).
If I have a creative flash, I want to put it in a shape immediately, not go waste my precious time on 'learning curves'. ( learning curves, taking model drawing lessons

)
For the user who wants to draw and doesn't want to download an illegal version of Photoshop I'm sure there are 'free' applications under Windows aswel. No reason to switch to Linux (Imagine you want to print your artwork and have to configure CUPS).
And don't give me Wine... (

give me whisky, a Coal Ila will do)
Wine is the Linux community admitting defeat.
Wine is saying that the real guys don't trust the viability of this linux-hype yet, so you need something that makes windows-stuff believe it's running on windows.
That doesn't suddenly make it a Linux-application. It doesn't prove Linux is good. It only tells Windows has the good applications/developers/software houses and Linux needs to imitate it.
If it runs under Wine, it doesn't run on linux. You can't use it as ammo for your cause. Otherwise I'll say that I can run Linux on VMWare, which I have running on Win2000, which makes Linux a windows application, ending the entire problem.
Wine is what clochards use to not see the truth.
Anyway...
Ojo
( And what is it with these 99.7 versions (distributions) for Linux? Is that camp so divided they break up in splinterfactions? It starts looking like a religion more every day. When will we see Fundamentalist Linux terrorists?
