It still is really wonderful! I use mine almost every day for little calculations I need to do. IMO a physical calculator beats using your computer as one in many cases.
I've long wanted to try the 50g, but haven't been able to forgive HP for ignoring longstanding bugs in the 35s and for outsourcing the design of the RPN calculators that they were rightfully renowned for. I ended up replacing my 35s with the "open source" WP 34s, which is based on the HP 30b calculator platform:
