While the iPAD is nice for running remote software, remote-recording, some soft-synths (albeit limited in capability),
Waldorf's Nave is well worth looking at and not exactly limited. Way cheaper than the plugin version as well. Same with some of the Korg and Arturia stuff, and iVCS3, perhaps the best emulator of the VCS runs on an iPad. Unfortunately they emulated the VCS's strangeness along with everything else, but I guess if it was easy to play a scale on it it wouldn't be a VCE emulator. Moog's modular 15 app is also pretty good even if actively user hostile.

etc... having to use iTunes to simply move data is **royal bass-akwards** 
It kind of makes sense if you're maintaining shared iTunes libraries - within the multi-user license restrictions imposed by media providers and creators - and maybe other data across a home (or other) LAN/VPN. Then when you throw the Apple TV into the mix it means all the Apple stuff is sharing from the same, predictable media server.
I guess it also means Apple can have some certainty about what iOS and apps were going to be interacting with and it helps provide support if even the most deterninedly awkward and clue-free user will be sitting baffled in front of iTunes, not any number of possible applications.
And it means every computer with iTunes installed gets lots of opportunities to but from the iTunes shop of course. Though Windows seems intent on taking that business model to new and further places with Amazon running along behind as fast as they can.
In the end, it is what it is. iTune's a decent enough media player and only has to be beaten into submission with a sock full of lead shot the once.
Some data can be got off an iPad into Windows by drag and drop without iTunes, if I remember correctly you have to tell iTunes to tell the iPad/phone to act as data storage device in Windows, though my memory may be faulty, it's been a while.
