By the way one of the main bugs are:
-Resetting the calc causes the calc to freeze
-Trying to delete all lists causes the calc to freeze
-In certain rarer occasions, on auto-power-down the calc will freeze instead of turning OFF. Didn't have this happen on the current firmware, though
-File transfer to/from the computer won't work under the latest firmware and the one that comes with the calc. You can view program/variables content from the computer, though, in read-only mode.
-The calc adjusts the CPU clock according to battery power. This can get annoying if your game needs a lot of speed.
-Connectivity Kit freezes when the calc is unplugged from USB.
-Programs are about 10 times larger than their TI-84+ counterpart. This means the 255 KB RAM fills up pretty quick.
