After watching NextComputing dance around the definition of mobile computing for so long, we're not all that surprised to see the firm tease its first suitcase-desktop sporting an internal battery. The headlining promise of two to four hours of battery life, however? We'll take the whole salt shaker, thanks. NextComputing's half-minute demo shows an unnamed workstation disconnected, unplugged, and lugged off. We're not really sure where it's going, or why it needs to be left on for the trip, but hey -- a desktop with a battery still beats a laptop without one.
