Mobility Electronics has launched the latest in its line of Stowaway portable keyboards under its Think Outside brand, the Bluetooth-based Stowaway Sierra. Ok, so it's not quite as catchily-named as the Stowaway Shasta, but it does look to be a fair bit more versatile, compatible with Windows Mobile 5, Pocket PC, Palm and Symbian-based devices (with Bluetooth, of course), as well as Windows XP and Mac OS X, for anyone that finds their full-size desktop keyboard a little too comfortable. Unlike some portable keyboards, the Stowaway Sierra packs decently-sized 19mm keys, including dedicated numeric keys and shortcut keys for your smartphone, PDA, or Windows XP -- yet it still manages to fold up into pocketable (depending on the pocket) 5.0 x 3.5 x 0.9-inch package. You can snag this one now for $129.99.
