I just renewed my TechNet subscription and grabbed the release version of Windows 8. I was going to wait until Windows Server 2012 was released and stay on the RC but then I got the itch. My main PC is an Intel Core i7 with 12GB of RAM, 2 SSD’s and a 2TB drive for storage. Needless to say it is pretty fast. Although I don’t have touch capabilities this PC, Windows 8 adds many features that plain ol’ desktop users like me can benefit from. There is also a huge performance increase too. Windows 8 is so much faster than Windows 7 in booting, launching apps, and even shutting down.
Microsoft is offering a free trial too (aimed at developers). You can download the 90 day trial of Windows 8 here. This trial cannot be upgraded to a full version and it will end in 90 days so if you do make the leap, be sure to try it on another PC/laptop you have lying around.
