Ubuntu is alright for people new to Linux but has become a rather bloated distro. I prefer FreeBSD w/ XFCE, (FreeBSD is NOT Linux), but if I had to choose a Linux for my desktop I would probably choose Zenwalk.
Sony, no - not natively, but many Windows programs can be run with a package called wine. Also, there are tons of open source programs available for every task imaginable - and they are often better than their Windows counterparts.
