I love my TI-89. Now Wolfram Alpha makes some/most things easier, but I still have a sweet spot for my TI. I still have my physical calculator in my desk drawer, but I also have 2 emulators for my phone [1] and my computer [2]. I think both require you to extract the ROM from your physical calculator, but either way, it's worth it if you love your TI!
