I want a custom calculator that has all the features (including a GPU, ARM7 processor, possibly 3D display (like HTC Evo 3D), WiFi (yes, SATs don't restrict Wifi!), SD card slot, camera, Android or Ubuntu compatible ... maybe OCR problem-solving?) possible except these by default (requirements for SAT, I'm surprised how easy it is to have an acceptable calculator

):
Calculators with QWERTY (typewriter-like) keypads (just switch the W and the Q to make it a WQERTY keyboard to make it easy to type but allowed at the same time)
Calculators that contain electronic dictionaries (doesn't mean disable potential for dictionary, user's responsibility)
Calculators with paper tape or printers (Allow network printing could work though)
Calculators that "talk" or make noise (headphone jack ok/slot to put internal speaker in)
Calculators that require an electrical outlet (Meaning it needs battery lasting for at least 48 hrs strait with display and simple math, underclock when not using android OS)
Cell phone calculators (as long as it's not a cell phone, it's fine)
Pocket organizers or personal digital assistants (As long as it's labeled as a calculator, it's ok)
Hand-held minicomputers, PowerBooks, or laptop computers (As long as it's labeled as a calculator, it's ok)
Electronic writing pads or pen-input and stylus-driven devices (the Sharp 9600-EL can be used without the stylus) (finger touchscreen is ok)
