The TI Nspire CX color display is very pretty, but my HP 49g, 49g+, and 50g with their monochrome displays have very long battery life with a few inexpensive AAA cells. The TI needs to be recharged quite frequently.
I guess if you are accustomed to charging your other devices frequently, then charging your calculator too might not be such a bother.
On the other hand, if the batteries in my 50g run low during an exam, I have a spare set in my backpack. With the TI, I'd be SOL.
If HP has put a higher-resolution monochrome display in the 39gII, the reason they chose that over color is almost certainly battery life.
Someone speculated that the 39gII display might have 16-level grayscale. I haven't seen a 39gII in person, and am not privy to any details about it, but I suspect that it will turn out to have hardware with no grayscale support, only high-resolution monochrome. That would mean no antialiasing on fonts, but since the resolution is probably around 173 dpi, it should look pretty good despite that.
Based on comments heard at past HHC conferences, I suspect that this is probably not running RPL-based software derived from the 38/48 series, but rather an entirely new code base in C and/or C++.
