Mitac's new Mio 168RS Pocket PC with GPS

Mitac is releasing their new Mio 168RS Pocket PC with built-in GPS in North America, which is apparently an update of their Mio 168 handheld.  Like the 168, the 168RS
comes loaded with a 300MHz processor, 32MB of Flash ROM, 64MB of RAM, and a 3.5-inch LCD screen.  They're also both the exact same size and weight.  For some reason, however, the Mio 168RS is now a hundred dollars more expensive, with a $599 list price, although it seems to be available for considerably less online.
