All day battery life in UMPCs? What’s that mean?

NewintellogosJust a quick point of clarification andor opinion so that bad info isn’t spread. I’m seeing numerous headlines like this one out of last weeks IDF conference regarding battery life in UMPCs. Most of the headlines state that we’ll see "all day battery life" in UMPCs by 2008. While the news is good and there’s no doubt Intel is planning to use much less battery power for the planned processors, let’s not get deluded with ambiguous headlines.

"All day" battery life could mean a 7 or 8 hour workday. Or it could be interpreted as an extreme 24 hours; something in between, even. Bear in mind that the CPU only uses a part of the battery consumption; other large energy consumers are clearly the screen (especially the backlight function) and the hard drive. Solid State Drives will help with energy consumption as will LED backlighting, but let’s be sure that the masses don’t misunderstand what "all day battery life for UMPCs" really is. After all, aren’t folks still ticked that UMPCs don’t cost $500 and allegedly can’t replace a desktop? That’s what happens when the hype and expectations aren’t managed. My expectation: if I can manage my power through appropriate settings and sleep/hibernation functions to get through an 8 hour day by 2008, I’ll be a happy mobile camper.
