I have been using Windows 7 RC1 for a little while on my laptop, as it’s only OS, and for the most part I think it is ready. There were a few issues I noticed but hopefully they got them ironed out before they put the code to RTM(Release to Manufacturing). Honestly, if you held off getting Vista but want to upgrade one day, wait until 7 comes out. It does take care of some of the nagging issues of Vista and overall seems faster. If I can afford to drop the coin necessary to get it, I will soon after it is released.
