I've got a test bed up for W7/RC1. W7/RC1 looks to me like Vista done right. It installed and runs cleanly (and decently fast) on a MSI Wind micro-notebook sporting a 1.6gHz Intel Atom HT CPU. Not exactly a speed demon, but only 2.5 pounds fully loaded. I didn't need any external drivers for the hardware, including the WLAN setup which was fast and flawless. I've got AntiVir, MBAM, Mailwasher, T'bird, FF, Java, Directory Opus and OpenOffice all working without any problems. Less than 2 minutes from turn on to desktop. That's hard to beat, IMHO!
