Weird...I heard this was coming and expected it to be on Connect but it's publicly available which is great news :) I hear from others that it's better than RC1 which really should be something. Off to download myself now whilst watching the Ryder Cup.
Note: "We are making this release available for a limited time only (and only by download) in order to get broad distribution and testing in a variety of PC configurations"
[update] I found via JCXP that the build is actually on Connect and is 2.6gb for the X86 version
Simple.
Format c:\ /q /u
then close you notebook in a box and return it to your dealer, saying "I'm fully stupid, and I can't use a computer"
Change your mind, why don't you take up knitting?!
