The Panasonic Toughbook U1 is a new kind of mobile computer, a one-two punch of Toughbook ruggedness with hot-swappable twin batteries for full-shift productivity. We wouldn't want to put words in your mouth, but being able to run Windows XP or Vista while still maintaining its convenient lightweight design is something other handhelds can't begin to imagine. Couple that with its seemingly endless integrated options like GPS, 3G mobile broadband, a 2MP camera and fingerprint and barcode scanners, and you might forget you're not carrying a laptop. We won't say we've reinvented the handheld. We'd rather wait and hear you say it.
