The way this works is that on another machine (or I guess on an existing OS on the netbook) you download a bootable USB key image. With some trepidation (not a whole lot, I did back up first), I put in the USB key and settled in to see how far I could get with the installation.
Well, a short time later I realised I'd finished installing and was really just fiddling! Straight out of the box the wifi worked, the hibernate worked, sound (in and out) worked, the webcam worked, and there is this great window handler thing which amalgamates title bar and task bar into one. There's also a cute menu on the desktop - all in all its really neat:
The working hibernate in particular has really made a big difference, at home the netbook just gets used for short bursts and lives next to my bed, usually plugged in. When it comes into its own though is at conferences! I can flip this thing open, use it, and flip it shut, pretty much all day. The startup time is really small from suspend and so long as I'm only dipping in and out (at conferences, I'm mostly in talks so I'm only ever checking mail etc), the battery life easily lasts a day.
Thanks to the Ubuntu folks - this is one quality piece of software and now I love my little netbook even more. Anyone else using the netbook remix? Were your experiences as good as mine?
