So far I'm getting the impression that the battery life estimates might be a little conservative. It will probably take a couple of weeks before I get an idea of what my average usage will be. It lasts a long time on on standby.
I'm really loving this thing. I'm going to have to dig around and see if it uses EFI intead of BIOS. The boot consists of a flicker of the screen, a couple seconds of black and the Windows startup screen. Overally it's pretty snappy. I'm a happy camper.
It could be a traditional BIOS POST but with the memory test and text-mode display disabled and instead with a black bitmap display.
I've read that EFI is not necessarily much faster than a traditional BIOS boot.
