I tried WLM, thought it looked awful, couldn't see any new features, found it put a 8GB (!) sparse file on my hard drive (real size 1MB) and promptly reinstalled 7.5. Very disappointing.
alotta the features i can't try out, because my family and friends are not caught on, there just hopin on the myspace wagon, i personally can't stand the cosmetics, the color schemes are just nasty, i like the current version, i just wish i could change the color on the buddy list like i can with the chat windows, or better yet, if it used my xp theme...so i don't have a dark xp theme, and a light blue chat window.... and this whole open dir thing they got going in the new version, i see alotta security flaws opening up there, where u can just let people d/l from a assigned directory, how long before that back fires??? but i guess we will see..
