I have a netbook (an older Asus EEEPC 1005HA) which I want to get rid of Windoze on (I like Windows, but I don't think it works well in a netbook environment).

Basically, my question is which Ubuntu variant will use the least RAM and CPU running idle, and/or the same question except when running Firefox and Libreoffice Writer, say.

I am also open to suggestions of non-Ubuntu Linux distros, but since this is AskUbuntu I thought the first question would be more appropriate.

I have a disk drive which I can attach to the netbook, so it doesn't have to be a Ubuntu Variant / Linux Distro which solely boots from a USB drive.

I have at my disposal: DVDs, DVD writer/ disk drive, 4gb flash drive, 8 gb flash drive

I was thinking either Lubuntu or Archbang / Crunchbang but I would like some help from more knowledgable people

Specs:

Can't boot into it right now, but I think I have either Intel Atom N270 @1.60ghz OR Intel Atom N280 @1.66ghz (single core, I think)

2gb RAM

160 GB hard drive
