Tony, you're right, the Micro is a good, full-blown, playable arranger for under $500. It's also probably something most players do not or have not owned (PA50 SD). So, instead of parting with $1500 - $4500 for a new axe, they can have this perfectly acceptable dagger. As for playing on the keys - it's anything but impossible. Novelty, yes; main axe, not so much; affordable distraction, for sure...
