Aside from the inevitable "it's dross" comments which I'll leave to others, A couple of neat things:
>>Anyone buying a PC from today will be able to upgrade to Windows 8 for $14.95, she said, and for the rest of us the $39.99 price tag looks set in stone
>>All customers will get access to SkyDrive cloud storage with a Windows 8 purchase
SkyDrive for free especially seems quite cool, depending how much you get. I do wonder though what happens if you already have a Windows Phone... can you combine your included storage?
