I know a few that will be able to install applications and make more use of it.
But the point is taken though, not to wade from the OP's question too much...
If it has to come down to Linux distributions, I'd pick Ubuntu myself and stick to an LTS distribution and no 3D bells and whistles. If I want something with more recent software and 64-bit, I'd go wit Fedora 16. That's just a guess based on what what I've experienced.
The point is that if you are picking Linux for your desktop/workstation you will be constantly changing it and you will come to rely on it to be working all the time and correctly. I do not believe that any of the distributions so far can provide enough reliability for that and what's why I voted - Junk
. The worst thing that can happen would be to get attached to the install and have it break beyond repair (or beyond you spending reasonable amount of time fixing it) at some point, so I'd really suggest to take Linux lightly and be ready to reinstall the OS at any time.
Also I would advise against doing any "automatic updates". Windows started this annoyance, but Ubuntu managed to excel at it. I think I was being nagged all the time with 120 "important" updates at one point about a month or so after doing the install an updating everything.
