Windows 7: Which to buy - Upgrade or Full for RC computer

Can someone explain this email I received from Microsoft this morning? It appears to me unless I am reading this wrong, that all Windows 7 RC user are eligible for the upgrade.

"You've been using Windows® 7 for a while now, and we hope you've been enjoying a simpler PC experience. Because you've been a loyal Windows customer, we're offering you the Windows 7 upgrade at a great introductory price* - only $49.99 for Home Premium or $99.99 for Professional. It's our way of saying thanks for trying it out. To take advantage of this deal, pre-order your copy while supplies last."

I think that microsoft assumes everyone is dual-booting with vista or xp, they have said in earlier statements that RC to retail must be a clean install. But that could change. But yeah, I think they assume we're all dual-booting. (I am lol)

that's the pre-order deal currently on offer at the m$ store

You can do a RC to RTM upgrade microsoft has said that here and in the windows 7 upgrade test matrix doc.

Yeah, if you click on the pre-order your copy link, you get this. That would indicate that the RC users are eligible. I will follow up with a call Monday to Microsoft.

Windows 7 is coming on October 22. Here’s an easy way to get a great deal. Pre-order a Windows 7 Home Premium Upgrade for $49** or a Windows 7 Professional Upgrade for $99.** That’s at least half off the suggested retail prices. This offer is available through participating retailers. Pick one below and pre-order today. They’ll tell you how to get your copy.
Then sit back and relax. Your hard work is being rewarded.

damn and I won't get it.

I have a Dell Dimension 8400 with XP. I plan to switch to Windows 7. Two questions: Is the 1 meg of ram on board sufficient? I do no graphics or gaming. Mostly web crusing. If my harddrive were to fail or I needed to replace the motherboard in the future would I have to have the full version of Windows 7?

1 GB (not meg) of ram is sufficient for your stated purposes.

I think there would be a way to reinstall the upgrade version if the failures you mentioned occurred. Worst case, if you couldn't reinstall, you could always call Microsoft and explain what happened and I'm pretty sure they would give you a special key or some way to get it working again.

Buying OEM is much cheaper and I just called TigerDirect to make sure it came with a key.

Curious... Why do you reply and resurrect 5 month old post?
