I install a new linux box today. I was impressed. Simple setup. Network, Video, right out of the box. It does what most need to do ... free.
Hardware was and old pentium 4 1.8 with 500 MB and IDE 40 GB drive where XP runs ok, basic throw away box.
I downloaded the iso and burned to CD since old pc didn't have DVD. Boot off CD and took the defaults, formatted the hard drive taking the listed suggestions.
(ok I didn't have to get out the book and remember how to mount and setup the swap file!)
Ubuntu 9.10 - the Karmic Koala
The new software center rocks, I was able to simply add software, update with GUI, didn't have to remember my ole unix/linux commands, (don't worry they are still there and you should learn them but not needed)
Right now watching video, browsing the web, and looking around new interface.
