Yes but not in terms of market share, unfortunately. Monopolies suck. The best solution would be a standard open source operating system that would run on ARM hardware with a wide range of RAM and display support, like Java apps on midrange phones in the 2000s. And a QWERTY keyboard when rotated (we need the law changed for that to be legal in US schools). And an OK, as well as a BACK or EXIT button like CASIO. On the TI, I've seen programs that use MENU, DEL, CLEAR, ALPHA, SHIFT+MENU (QUIT), ON or a menu item confirmed by SHIFT (the usual OK key in games) to exit.
