From one of the ads served up on this blog, I find a fascinating deal: buy a PC from a local builder with genuine Windows XP, and get lots of prizes worth up to $615. But wait, the average PC costs about $615, so that means you get a vacation and a free PC.
Served up at Microsoft Windows Marketplace, this appears to be a real marketing campaign -- as opposed to "click here and win a free iPod" scams. But I'll be damned if I can make out the economics.
So, hey, support your local PC builder!
[Full Disclosure: several of the hosts of the On Computers Radio Show are PC builders]
