I play both PC and PS3. Almost always PS3 because i can relax on the couch with a controller in my hand and a wireless keyboard at the table for communication. When grouping with friends i bring my laptop for Xfire. Obviously PC version looks better and is much faster with loading times (think SSD in my PC also helps), but my preference goes to PS3 for playing relax on the couch.

Yes i can use my gaming PC on my TV screen in my living room, but i don't want to move it everytime i want to play FFXIV.
