Ok, so, I'm very interested in the Galaxy Tab (mainly because of the perfect size and os), so I asked my friend about this situation and he said that since there's recently been a decision to allow cross-converting compilers (including iPhone apps); Most apps are likely to cross over to Android.
I told him that I wasn't sure until I saw at least 50% of the apps I frequently used on the android market so we did a little search and we found less than 10%.
I'm just going to wait it out until January, then I'll make my decision.
Give G-Stomper a try. It's an Electribe like 11-Track Drum Machine with a powerful effect chain (3 processors, 17 effect types). Live Pattern Arranger, Song Mode, Motion Sequencing, Audio import/export, SoundCloud integration, and much more. Available at google market (free demo and full (paid) version). http://www.planet-h.com/gstomper
I tried Jasuto on "that platform that we're not mentioning here" and it should be exactly the same as all other platforms.
It sounds really good and lots of possibilities, but I found it really hard to get into so I gave up.
