Everything is working very well, with the exception of the built-in webcam, which I have never used. Sound, wireless, 3-D graphics and more are working just right. Keep in mind, this is still a beta version; when this becomes gold, it will be Mepis 8 and rock solid as usual.

I have been using the 32-bit version since December 2007, and have been extremely pleased with it. The base install is great, but limited in a few areas. It comes with enough software to get most people up and running in about 20 minutes or so, unless you have to do some partitioning work. If I ever have to reinstall, the whole process is only about 10 minutes or so.
