GadgetMadness: We find the coolest gadgets first

You've seen this virtual laser keyboard before but you couldn't actually buy one - until now! The wait is over and ThinkGeek now carries the Bluetooth Laser Keyboard! This awesome gadget uses a rechargeable battery that lasts for 120 minutes of continuous typing, is only 3.5 inches high, and works with PalmOS 5, PocketPC 2003, Windows Smartphone, Symbian OS, and Windows 2000/XP (limited Mac OSX Support.) I've always wanted one of these, yet see a big problem with this keyboard. If the battery only lasts for two hours and has an internal rechargeable battery you'd have to wait for it to recharge before using it again. If it took regular AA's, you could swap them out and not have to wait. The virtual keyboard does come with an AC adapter though, so it's possible it may work while plugged in for extended periods of time.
