Haven't bothered to check (in the middle of updating iTunes now), but does the iPad version offer significantly much more functionality to justify being twice the price of the iPhone version, or is it just optimized screen resolution?
I love my iPad, but I feel I'm getting gouged.
FM on the iphone is great checking data or making a quick change. BUT
FM on an iPad is a replacement for FM on a PC. Just for inventory use alone this is going to be a killer system. Hell it wouldn't be totally unreasonable to buy iPads just to access FM. Compared to FM for the desktop your saving $250 half the cost of an iPad.
