i haven't tried fc2 test2 yet, and test3 is out now. test 1 was almost unusable though.
when fc1 was coming out i used both test2 and test3, and both were pretty usable. i would wait a couple of days and see what people are saying about test3. if it seems pretty clean and useable, more of a release candidate and less of a test then i would go with that, and upgrade to fc2 final when it comes out. there _shouldn't_ be too much difference if they are doing things the same way they did with fc1.
ive been doing dual boot on my laptop for a long time, and try different distro's all the time. last night windows blew up my one permenet partition that i kept all my important stuff on. so i decided to give linux the whole drive, and use vmware for stuff i need. i decided to go with fedora because despite the bloat, its the best supported linux distro. and its updated more often and easier to obtain than suse.
so im going to wait for fc2 final. im really looking forward to using gnome 2.6 again. i used it some under slackware and its very nice.
