I've actually thought about trying to for the 360 a few times, I just don't feel like blowing the full money on the game. If I ever see it for rent again at Movie Trading Company I'll probably rent it just to try it out, though I know playing that version would always be my last resort to playing because I can't use a keyboard (and not buying the chatpad thing).
Right now I have it set up on my crummy computer in my home office, my W7 laptop, and I might install it at work just so I can skillup my SMN skill in the background (it's close to cap but now that it does something really useful I want it capped).
-edit-
For anyone that cares, the two new-ish things that SMN skill affects:
Elemental Siphon-- Take MP away from your spirit (yes, spirit, we finally have a reason to use them!). You get more or less depending on the spirit/day/weather and also your SMN skill. If you get your SMN skill over the cap you start getting nice bonuses. It's a 5 minute ability and I generally get about 170MP if I just use any spirit and more than 200MP if I use the correct spirit because my SMN skill is already pretty high (about 30 away from crap). One time I used it in the correct weather/day/spirit and got over 300MP back.
SMN skill also directly affects your avatars accuracy and damage on the level 70 BP's for every point you're over the cap now, though I haven't seen any formulas for that.
They've also made it so that when you use Blood Pacts that can level up your summoning skill rather than just endlessly sitting by a zone and casting avatars.
