I've been testing Windows 7 beta build 7000 for the past couple of days, and will be posting my personal take on it shortly. So far, I am more than impressed by the installation, device drivers, performance, and overall user experience. You should definitely give it a try - there's a free download of Windows 7 Beta that's available now.
In addition, I'd like to offer you the top sites about Windows 7 and where to get Windows 7 planning and deployment tools...
