Yes! Finally a little of 50 Cent/Kayne action in the world of gadget technology. No surprise here, the throwdown is coming directly from the tech world's resident gangsta rappers, the PR spokespeople.

Microsoft has been talking a big game in light of their recent Zune 2 announcement, suggesting that the new line of players might secure them the second spot in the world of DAPs (not number one? Come on guys, you call that braggadocio?), after the coming holiday season.

SanDisk spokesperson, Carmella Lyman, has just throwndown, hair-first, promising to shave her head, should the Zune bump up to number two after Xmas. Of course, it's not much of a bet if it's not a two-way street. MS's entertainment and devices president, Robbie Bach, who supposedly made the initial declaration, will have to agree by Halloween that he will shave his own head, should the devices' less-crippled wi-fi put them over the top.

We, for one, welcome the move from empty bragging to ill-advised wagers.

More Zune tats, anyone?
