We know it's the N900 you're jonesing for, but if you're looking to let those "other guys" put Maemo 5 through the ringer while you continue to use an OS that's been around the block, Nokia's got two more for you to choose from starting today. Both the QWERTY-packin' E72 ($407) and eager-to-route 5800 Navigation Edition have started to ship to America (according to the company, anyway), with the former listed as "coming soon" on Nokia's webstore and as "in stock on December 10th" over at Amazon.
