Microsoft's Windows 7 honchos recently showed off the power performance improvements of their soon to be released OS, playing a DVD on a Vista Ultimate and Windows 7 Ultimate laptop side-by-side. The Vista notebook showed 4.14 hours of life left, while Windows 7 offered 5.5 hours. The catches? Those improvements come by way of Intel-specific engineering, and Microsoft said real-world performance is due to vary based on other hardware. Still, it's worth knowing if you're the type to turn a flight into a cinematic marathon. [CNET]
