SuSE is a good distro, but before you buy the 10.1 version look around the SuSE forums and the general ones. There is one huge nearly show-stopping bug in the new Zen-updater software, such that it crashes or gives you non-existent dependency hell when it tries to download and install updates. A bug-fix has long been available, but if you try to install it with Zen.... you get my drift. :wink: You can, of course, use YaST or the command line, but a newcomer wouldn't know that.
There are several other issues such that many SuSE users are sticking with 10.0 and waiting for 10.2, or have come over to Ubuntu. :) - myself included.
All you get with the retail version are properly pressed disks, a pretty manual and 90-days support. Limited support - read the small print. As far as I know there's no difference between the 32-bit package set between the retail version and the opensuse version so long as you download the addons CD (contains some proprietary stuff).
