I still prefer a TI-89 compared to almost anything else.

@Robotbeat The HP-48GX was peak engineering calculator. I gave mine away, but still use the emulator on my phone. The thing was built to survive in the field. Too bad they never made an updated version. Hp-49 doesn't count its like the matrix sequels.

@codingfodder @Robotbeat Yeah, I still have my HP-48G+, but use Droid48 on my phone.
