It takes ages to cold boot. My desktop is ok-ish, but it doens't matter since I only use it occasionally.

My old HP laptop had a slow-ass BIOS that I was convinced had some kind of bug. I replaced it with a brand spanking new thinkpad 2-3 months ago. Guess what? The freaking BIOS is EVEN SLOWER somehow!

They all wake up instantly from sleep.

I therefore only shut them down when I know they'll be unplugged for a while, because for some reason the HP eats through the battery even when off. If suspended, the battery will be out of juice in like two days. Haven't tried any of this with the Lenovo yet.

Suspend used to work great, but since MS figured they should copy Apple half-assedly, suspend is borken. And I have really no idea what we've gained in exchange.
