That may be what sg_oneill meant, but that's not what I meant in the post that sg_oneill was replying to. NotRobot is talking about exactly what I'm talking about — using a tablet for reading sheet music while I sing or play music on an actual physical instrument.
The best part of the Android tablet experience is that MobileSheets lets you have two tablets side-by-side and sync them with Bluetooth so that you can turn two pages at once, so that you get to the spot where the publisher (hopefully) left time to turn before having to deal with it. That costs $320 with basic Android tablets, or $1500 with iPads (or $1660 for iPads with cases to match the Android tablets).
To be fair, I *do* compose music, record music, etc., but I do all of that on my Mac, not on a tablet. Tablets are simply the wrong tool for the job.
For recording, iPads don't have nearly enough storage for recording, and don't provide an easy way to back up locally, which makes giant audio files a no-go.
For composing, I can't imagine doing it without a physical keyboard, because keyboard shortcuts are what make that survivable. And Apple's keyboard for the 13-inch Air is a $280 add-on. Worse, even if you do that, you'll still have a tiny 13-inch screen, which IMO is undesirable. And if you can tolerate a 13-inch screen, a MacBook Neo would still be $400 cheaper than a Wi-Fi Air with keyboard and is vastly more capable.
Also, even though I'm slowly starting to get used to non-discontinued score editing software, 100% of my existing compositions were done in Finale, which has no iPad version at all. So for working with all of that content, an iPad would be basically useless. Given that it was one of the most popular music editing apps for a very long time, I'm not alone in that problem.
