Although i'm 50/50 on showing the price on the button, i absolutely see your point! I think for devices that are "known" - like, say, a pair of headphones - i suppose i might want to know the price right away...however, for other "unknown" devices, i'd actually like to learn more about the product, its features, maybe use-cases, etc...and as one other person rightly noted even the "Why" i might want/need the product...then again, all of this info could still be shown, and displaying the price shouldn't harm that...so yeah, i gues you're right: they should show the price on the button. :-)
