I've no idea if what I do qualifies as serious, but yeah, I use my ipad a lot.
If you are poor, know nothing of musical theory, but still like to make weird noises with unconventional music apps (all of these apply to me), then the ipad will be your best friend, actually. There are apps available practically for free that are so good I almost hesitate to recommend them, for fear of losing my advantage. :p
But anyway, can you be a bit more specific regarding what you are after?
