Just installed it, looks good, the new Internet Explorer is really fast, much better than the actual firefox and supports tabbed browsing too ... but you techfreaks probably all know that already :-) ... before I used to have Win2K for like 6 years, recently a friend of mine upgraded to a new MAC with OS X and I wasn't anymore as satisfied with my old looking OS, the news headline that Vista RC1 was released came in the right moment ;-) ... my Hardware Athlon 3200+, 1 GB Ram ... running fine so far ... still need a better gfx card (something like 6600 GT probably is sufficient for my needs) and maybe upgrade to 2 GB RAM, some day ;-) ... Microsoft developed this system for 5 years, I really believe it will be a good OS, just like Win2K ...
