Partial years work just fine.
Whether you get one with the new firmware is a different question. No way to tell from the outside if it has it or not.

Nope. Still broken. Just picked one up, made sure there was a return policy on it. Firmware 4 5 2010. But, but... I am buying this in Nov 2012!!
Taking an example for DBXover from the HP12c user manual:
Cost: $11,000 / Salvage: $500 / Life: 8 years / 200% declining-balance factor / 6 months remaining.
Doing a full depreciation on the 30b works just fine:
1: DEP = 2750.00 RDV = 7750.00
2: etc...
Tried doing the partial depreciation, the right answer is:
1: DEP = 1375.00, RDV = 9125.00
2: etc...
The HP30b returns:
1: DEP = 1604.17, RDV = 8895.83
2: oops!
The whole partial depreciation schedule is shot to hell.
It is really too bad, I really, really wanted to like this calculator. I really do in fact, but... who knows what other bugs are lurking in there. HP's QA process seems to have broken down on this product line.
So, off to the tried and true TI BA world I go... no RPN, no programming. Sucks.
Thanks for the help though, I appreciate it.
