I am thinking of getting a 50G and I am wondering if in any aspect the 49G+ could be better than the 50G? Also where is the best place to get a 50G?

The keyboard of the 50g is much better than the early / mid 49g+ machines.

The color scheme is much better.

Otherwise, it is a 49g+.

To add a couple of other comments:

The 50G also has an RS233 compatable serial port (well to most, not so fussy RS232 devices). No cable is readily available though.

You use 4 batteries vs 3 for the older Hp 49G+. This should result in longer life between battery changes.

Keyboard is significantly better than all but the latest last year production of Hp49G+s.

USB is now powered from PC which can theoretically extend battery life. However, the typical user doesn't keep his Hp tethered to a PC.

Thank you all! I hope by not getting either the 48GII nor the 49G+ and simply getting the 50G I won't be missing anything.

So far as the cable goes, the serial port uses a non-standard
("captive") "4-pin USB mini-B" connection. No doubt one could
build his own level-shifter.
Samson Cables is
supposed to be planning to market a suitable cable/adapter real
soon now.

The serial port also provides a connection to the battery
terminals. This is supposedly for an option to provide power to
whatever the user chooses to connect to the port, but, with a
non-rechargeable battery disconnected, could be used to power the
50g, or with a rechargeable battery installed, could be used to
recharge the battery as well.

The 50g can also be powered through the USB port with a 5V
adapter, such as the ones available for various music/video
players. The 50g requests 50mA from the USB, so any adapter that
can supply at least 50mA at 5V should be okay. I don't know how
much current the 50g actually draws; I expect somewhat less. I
expect that the highest current requirement would be when writing
to flash memory.

Note that the 49g+ and 50g seem to work well with NiMH cells,
except that you won't have as much time between a low battery
warning and the battery going too low to work at all. I suggest
keeping a spare set of AAA cells easily available if you use
rechargeable cells, but using them should save on battery costs.

For that matter, the 48 series and the 49G also seem to work okay
with NiMH cells, but the battery life is usually much longer with
those models, so I think that alkaline cells are usually more
appropriate for them.

The 50g uses the same (flash memory) "ROM" as the 49g+, so except
for using system flag -78 to select whether the "via wire" I/O
uses USB or the serial port, programming should be the same.

Gosh, I hope the battery life of the 50G is better!

I put a fresh set in my 49G+ just a couple of months ago. Being more at home in old-style RPN, I use the calc very infrequently. I use a "BAT" app to track battery life. Last I remember, I had 80% of battery life left. Now a few short weeks later, I am getting a lowbat warning. And this is just from mostly sitting around, turned off.

Sheesh! Can't imagine how many batteries I would eat if I used it as my main calc....

The best price I've been able to find on the 50g is at Buy.com. Free shipping if you don't mind waiting a couple of weeks.
