I'm a 44 year old man and I would love this - for years I've tried to dabble with music with much lack of success - but this looks really fun to play with. Great job.
Go grab a Teenage Engineering Pocket Operator, it's definitely worth a try !
I personally recommend the PO-33 (KO!), it is fun and easy to play with :)
The POs are fun to play with, but from experience I would much rather recommend getting a used mk1 Novation Circuit. For $150 - $200 you have a four track drum machine plus two tracks of a great synth engine, with a built in mixer and simple effects, midi in if you want to use a keyboard, and the thing is still compact and battery powered.
