>hated dealing with a laptop

Can you expand on this, as im having a hard time comprehending. At the least, a laptop is a tablet with a built in stand :). How is a laptop hard to deal with?

It's probably the immediacy. You click an app and you get a fullscreen touch UI with no distractions. Quite different to opening a slow-loading DAW and starting up various plugin windows inside it.

iPad music apps are typically priced far lower than the equivalent PC apps, and there's a thriving community of iOS-only development as well.

For me it's the sweet spot between hardware (which is expensive and annoying to cable up) and PC VSTs (I associate my laptop with work). The fact the iPad can also be used for videos/books/drawing/note taking is just a bonus.

I prefer music production on a laptop, so I'm not the target audience here. But it's so easy to pick up the iPad and noodle on a synth for 5 minutes.

And the music you write is infinitely better than the music you don't. Anything that inspires gets extra points for that alone. :)
