Hi,
I have been a happy Linux user for about 8 years now. The last 3 years I've used LinuxOS, Mandriva and Ubuntu except for.... Photoshop. I use GIMP a lot, but Photoshop is really so much more powerfull. And GIMP ergonomics are not really my tast either. I only use the GIMP because there isn't really anything else in Linux. Photoshop CS2 under wine works, but veeeeery slowly. So I keep a dual boot exclusively for Photoshop and Lightroom.
I make my websites with joomla (e.. Dead Link Removed), and the latest 1.5 version is really everything I need. For years I've used Homesite, Frontpage and Dreamweaver. But Joomla is simply the best there is at this moment. Very stable, losts of great plugins, a very large community, and a joy to use.
