I am normally one of those people who gets very annoyed with Microsoft quite quickly. But Vista RC1 is a GREAT improvement from BETA 2. It took around 20minutes to install (BETA 2 took almost 2 hours). My system seems to load Vista RC1 almost as quick as it does XP.
Only problem is WLM. A few bugs with their 'server' there (which only seens to occur when using Vista, and works OK in XP).
