I had no problems at all with this deal, but I also installed it over a working OS. The deal was very specific about it being an upgrade only without a physical disc shipped to you. I downloaded it at work (1.4Mbps on our fat pipe), extracted the files to a USB stick, and once I got home I double-clicked Setup.exe to get started.
I was able to do a semi-clean install, moving all my stuff to a Windows.old folder to blow away later, so you aren't forced to do an in-place upgrade with all the potential problems that brings. My Win7 beta was running really slow so I ended up doing a clean XP install first with a re-format then immediately installing Windows7 over the top of that.
If you absolutely must have a bootable DVD to use, you can either download the Windows Automated Install Kit to make your own custom DVD or you can follow the shortcut directions at this link:

After all the comments this week claiming how much smarter Tom's Hardware readers are than the average Joe, a few work-arounds shouldn't be any problem, right?
