Now that Windows 7 has launched into pre-Beta, Microsoft has joined the world in Vista-bashing as they look to differentiate their newest OS from the incumbent.

In addition to an overall reduction in the number of services launched at startup, faster booting is achieved by loading device drivers in parallel instead of sequentially. Windows 7 also manages wireless radios better allowing them to drop below 100% power draw while managing the connection. And by tweaking the OS kernel, the CPU can run sometimes run at a lower frequency and stay idle longer. This results are a minimum of 11% better battery life for Windows 7 compared to Vista -- and we're still
