PSP (US) preorders have commenced

We're receiving reports that Gamestop started taking preorders for the PSP yesterday.  Looks like you'll have to make a minimum investment of $50 to ensure you're very own device come March.  Yes, that's an unspecified date.

We perused the Gamestop website, but could not find any evidence suggesting that we could complete the transaction online.  Has anyone actually preordered a PSP at a Gamestop outlet or another US retailer?
