Rick mentioned the other day that the Vista Customer Preview Program is taking new registerations. If you signed up, or if you have been beta testing Windows Vista for a while now, you may be interested to know that the latest build, 5728, is now available. You can use your Beta 2 key and upgrades are supported from RC1. So what are you waiting for?
If you aren't on the beta you can still register and get Vista RC1 as well as Office 2007 and Exchange 2007 betas from BetaCentral. The time is near, launch will be here before you know it and you don't want to be left behind!
If you are running Vista and/or Office 2007 in a production enviroment (even if it is just one or two PCs) send me an email, I'd love to hear your experiences!
