ubuntu is the aol of linux, but it's a nice operating system.
i use windows for photoshop, flash, visual basic, etc, so i don't run linux very often anymore.
www.vmware.com (free) lets you run windows inside of ubuntu, but it's awful if you have graphic design work to accomplish.
if you
really want to jump on the ubuntu bandwagon, dual boot so you can use windows also.
unless you don't really need anything on windows, if that's the case, just wipe your drive and install.
cliffs:
linux = faster/safer
but i'm accustom to winows software, so fuck it
