It really depends on what you consider user friendly. If you want fast access to the top ten applications you will normally use and an OS that is almost entirely hidden go for crunchbang (http://crunchbang.org/) (video demo http://www.youtube.com/watch?v=KBuqWPcsTig&feature=relat...) . CB has been my distro of choice for several years now.
Crunchbang is pretty awesome on low-end systems, too.
I recently tried about 10 different "lightweight" distros on an old P3 with ~128 MB of RAM, and Crunchbang was the only one that ran ok and felt polished. (IIRC puppy linux was the only other one that ran fine, and it's just hideously ugly.)
My favorite distro was one that prominently mentioned that it could run on low end systems like mine. It turned out that the installer needed more RAM than the distro... I suggested to the developer that this be mentioned on the download page, and he seemed confused/offended! :(
