Setting aside printer capability, to a lot of users, wifi would be a top requirement for "working out of the box", and unfortunately i3 MK3S+ didn't have it before Bambu hit the market. On one hand, I understand how they ended up there, because their contemporary rivals Creality and Anycubic didn't include it either, and most of their userbase understood that they needed to run Octoprint on a Pi Zero or buy Prusa's wifi module. But on the other hand, if anyone did any bit of market research, they would realize this is quite an abrasive purchasing experience for a $10 wifi module. It just felt stingy.
