As of 12PM Pacific time today (as in right NOW) the download for Windows 7 Beta is available to the public!
(I'm downloading it right now) 2.5Gbs for the 32bit version & 3.2Gbs for the 64bit version.

So far the download is at full speed for me...that's because the servers are so jammed up with people trying to get to the download & not being able to not having the direct links like below!
Update: It appears that
Microsoft.com is suffering badly with "server too busy" messages but we now have direct download links below.
Edit: I just checked & they STILL are too busy to get through to the downloads so these direct links are your best bet!
Download: Windows® 7 Beta
x86 (32bit) and
x64 (64 bit) Windows 7 Beta 1 Build 7000 DVD ISO Image
Update: Seems even after you download from the direct link that you will still have to go through
the process of acquiring a key for it & the "Official" download site has still not posted a link to the Beta...(Wish I knew this a few hours ago...as I've got 2/3 of it downloaded now)
This is what they have there instead...so maybe by 12 midnight? Who knows...I'll post back when I know more,
but so far there has been NO download experience much less a "Quality" one on the
Official Download Site...

So they are yet to post a link to the beta download!!!
This is just Retarded considering the time they had to get ready for this...& yet is another example of MS stupidity...
"Thanks for your interest in the Windows 7 Beta. The volume has been phenomenal—we're in the process of adding more servers to handle the demand. We're sorry for the delay and we'll re-post the Beta as soon as we can ensure a quality download experience."
