PCLinuxOS Phoenix Test Run
Still looking for a more complete workstation for my laptop (although if I get openoffice working on puppy I may just stick with it). I think GNOME and KDE might still be a little sluggish with only 512MB RAM (though I've ordered another 512MBs so then it should be fine). Fluxbuntu and Crunchbang were very fast desktops featuring the Fluxbox and Openbox window managers, but I could not get either to work out-of-the-box with my wireless card (BroadcomBCM94306MP).
I have tried PCLinuxOS in the past and found it quite user-friendly so I thought I would give it a go with one of it's derivatives: Phoenix (PCLOS Xfce).
Pros: Live CD works well and allowed me to test critical aspects such as wireless detection, available packages, etc. Wireless card was easily configured with a BCM ndiswrapper.
