Core Duo Not Supported by Mac OS X Lion

So, I plugged my Macbook to the network, thinking I'd download and install Lion via the App Store (by going to Store --> Purchased (since I'd already bought and installed Lion on the iMac), but found that Core Duo machines aren't supported:

WTF...

It looks like my Macbook now has one foot in the grave.  I'll have to stick with Snow Leopard, but eventually, that will be unsupported.  It's not a huge deal, I guess, since Lion just came out.  I wonder when Leopard goes end-of-life (if it hasn't already)...

This is a rather large bummer.  The laptop isn't THAT old.

Well, there's one other Macbook in the house...my wife's.  It is a Core 2 Duo machine.  I don't even know if she wants the upgrade but it is available to her if she'd like to give it a shot.

It looks like I've a good excuse to buy me a new Macbook next year with whatever bonus I get.  If I do, I'll go Pro this time, more than likely...so I can game on it.

May as well back up with Time Machine since I've got it set up beside the iMac, though.
