nice meme and description, both here and on imgur.
Math Memes
Memes related to mathematics.
Rules:
1: Memes must be related to mathematics in some way.
2: No bigotry of any kind.
Casio is superior
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.
I'd buy the fuck out of an open source calculator
There are some open source graphic calculator projects but they aren't mass-produced and none are exam-approved. Software support is lacking but TI-84 Plus emulators exist so if someone rewrites TI-OS and the ROM (or requires people to dump it like the current ones), it could run that.
Did you know the humble Nokia 3410, the first Java phone, would dither games meant for higher-resolution color screens? Of course, programs for these calculators could use semi-vector graphics like the Web, or detect screen resolution and support the common ones natively, in a single or multiple executables like PocketPC software.
