I'm using PC-BSD for everything = internet, word processing, reading spreadsheets, pdf's, printing on an old LJ-5 that connects directly to the network switch, burning & watching DVD's.
The only thing I can't do is play Guild Wars via Cedega or Wine, so I'm running my 2nd machine on Ubuntu for that one reason...
I know that it won't take too long before I will be able to play GW via PC-BSD too, & then I can dump linux, though I will still continue to be involved in the excellent Ubuntu community.
I am grateful to Ubuntu, it gave me a way out from windoze. Now I have found PC-BSD & like it more than linux that doesn't mean that I will ever bad mouth linux, I remain grateful & helpful to Ubuntu where I can be...
