While I am waiting for the hoped for SATA Linux solution, I have been using SUSE Linux from a DVD all day. I managed to get e-mail working nicely, access networked Mac files, and print to my networked printer. All of this was done without any attention to a manual.
The Office package included is certainly more than I need. I was unsucessfully in playing a music cd, but I am sure that is just a driver issue.
The feel of the OS is very good. The browsers are both snappy. I prefer FireFox but it is pretty easy to like the one that spawned Safari.
I am much more comfortable in the Linux world than I am in the Windows world.
I am also very impressed that I can actually do work from a DVD based OS. That is really pretty neat. Talk about a safe OS. It is pretty hard to screw up the basic OS if it is running off a DVD.
I highly recommend giving SUSE a shot if you have a Pentium box around without SATA drives.
