I used ps3 with motion joy for some time. There is also the official FFXIV white controller that I bought, and I wouldn't recommend you get that. The dead zone shifted in the right analog, making my camera constantly turn. I didn't like the 360 controller because the D-pad isn't reliable, and I'd accidentally hit up and down delaying my inputs. I was more comfortable with my ps2 controller though, since I also used that for FFXI. I even set up my button inputs the same way ^_^.
I just purchased the U boost and It arrived today. The battery on the controller isn't very good I'm afraid. You'll get about 2 hours of constant play. U boost apparently doubles it. The battery pack isn't available yet as amazon has it listed as "Usually ships in 3-5 weeks," meaning the product isn't ready I guess. The Uboost along side the battery pack is supposedly able to give you 20 hours of game play.
As for the keyboard, I wouldn't recommend it. It's would be slow. The letters don't have much distance between them. Unless you type using the stylus, you'll spend more time correcting typos than conveying your message. Edited, Feb 23rd 2013 3:13pm by GDLYL
