I recommend SolusOS 1.3, which is Debian Stable with a newer kernel, and up to date software. SolusOS as usable as LinuxMint, minus the spyware-ish LinuxMint search. The Head developer for SolusOS used to be one of the bigger developers for LinuxMint Debian Edition until he had a falling out with the Mint Staff. --
SolusOS uses GNOME 2.30 as a Desktop environment, and if you use it, you will find that the desktop layout and default installed apps are much the same as LinuxMint.
As far as lightweight goes, SolusOS can be trimmed down much more than LinuxMint, and according to the GkrellM system monitor, my system and desktop only use up 70MB Ram. Unlike LinuxMint, desktop compositing and Compiz can be turned completely off and uninstalled without creating dependancy issues. Broadcom and Atheros driver modules are present in the kernel though Nvdia and ATI/AMD 3D graphics driver modules still require a download like most other Linux Distros.
I've been using SolusOS since May of last year and have had no issues with it.
My current system is a Panasonic Toughbook CF-T5 (MkII), spec'ed :
Intel Core Duo U2400 @1.06Ghz
1.5 GB RAM
Intel GPU
IDE HDD.
With Linux, my system actually runs faster than it did with the WinXP Pro that came with it.
FWIW, I like Crunchbang Linux a lot, and have Crunchbang 11 installed on another drive, but I wouldn't call it a 'newbie' distribution due to the fact that to configure it, you need to use a text editor to edit configuration files and scripts. --If you feel up to this, and are familiar enough with reading code, then you might like Crunchbang as well, but I wouldn't recommend it for a complete Noob.
