Considering just how many copies of Windows Vista that Microsoft has moved, it's not too surprising that a few (potentially rightful) whiners are calling the new operating system out for glaring issues. Not too long after users were complaining over sluggish file movements and bogus ads, it seems that the Aero Glass interface is the latest target of concern. Reportedly, the battery life of laptops is being diminished by having the eye candy cranked up, all while Microsoft claims that the OS touts "improved power management capabilities." Of course, Core Duo users cried this same river when trading more horsepower for minutes, but engineers from HP and Lenovo have actually concocted their own power settings after finding the canned options unsuitable. Still, it seems to make perfect sense that flipping on a glitzy interface that obviously requires more juice to run correctly would negatively impact the battery life, but until we start strapping potent fuelcells into our portable machines, this unfortunate trend is likely to continue.
