u know i use bm2 and nanostudio and alot of these apps on my ipod touch, and have been torn as to getting a ipad, but i decided,. I have a mpc500, i like using it better then my 1000, bm2 is kinda like1000jjos2xl, but the feel aint like the 500. the fly aint even out yet, so u dont know how good it will feel,. but think about it, u gotta buy a ipad, u gotta buy the mpcfly and they are gonna charge hella for that, the apps are cheap. but u can find a second hand mpc500 for cheap, and u aint gotta have 2 things like the pad and the fly.. battery life on my ipod touch while running an app like beatmaker 2 sucks, i barely get an hour or 2. on my 500 i dont have to charge the batteries for days, i tend to keep the screen backlight turned off on my 500 to conserve power, i have some energizer rechargables... also a plus about taking the 500 around with u is all it does is make beats, this way u are not wasting ur time on the net,playing games, or doing anything else on it except making music.. its a toss up, but I say with the 500
its easier and feels a lil more ol`school.. just my 2 cents
