Programmable Yes, in RPL. The programming model is similar to the HP-28S and HP-49G.
Performance Index The performance strongly depends on the calculator settings:
Numeric Trailing decimal points Performance

checked no 13

unchecked no 18

- yes 136
HP-50g unchecked yes 260
"Numeric" can be found in the HP-49G MODE/CAS settings. When checked constants are replaced by values which apparently slows down execution.
"Trailing decimal point" indicates how integer numbers have been entered in the RPL program: Either with or without trailing decimal point. If there is a trailing decimal point the number is automatically treated as floating point whereas without decimal point it is a long integer. Using long integers seems to be very unefficient!
Note that if the "Approx" flag is checked in the MODE/CAS settings than trailing decimal points will be added automatically to every integer number in a program when the program is entered - but not when the program is executed. So checking the "Approx" flag doesn't help to speed up a program that doesn't have trailing decimal points on integer numbers.
It must be ensured that integer numbers have trailing decimal points in order to achieve optimal performance.

Forensic Result 8.99999864267 obtained from a HP-50g
Comment A rather big and very powerful machine.
HP-49G with ugly rubber keys with no feedback at all! Unfortunately, it is completely impossible to use the unit without a manual. The key labels aren't self-explanatory at all. In the beginning the unit felt rather sluggish. However, after I reduced the keyboard response time using a "300 ->KEYTIME" command this is much better!
www.dynatech.de offers a HP-49G SpeedUp kit which over-clocks the CPU by a factor of 2 or 3. Apparently, the speed-mode can be turned on and off. The disadvantage is that the date & time functions don't return correct values any more.

HP-49G+ keyboard with its hard plastic keys is much better than the HP-49G keyboard but still cannot rival the traditional HP keyboards. Furthermore, the key clicks make a hollow sound inside the plastic housing which gives a quite cheap impression. And finally, feeling the key click doesn't necessarily mean that the unit recognized the keypress! Sometimes the click occurs but the key has to be pressed a little harder before the associated action is executed. This makes it impossible to type without looking at the display.
The display is significantly larger than in the HP-49G so that 7 instead of 5 stack entries can be displayed.
Note that the keyboard layout of the HP-49G+ is identical to the HP-48GII. Also, the software versions are (more or less) identical suggesting that the only real difference is the additional memory and the SD card slot of the HP-49G+.
Both the HP-48GII and HP-49G+ have a strange behaviour where the display seems to be redrawn about 3 seconds after the last change of the display contents. This is especially nasty when the blinking edit-cursor is visible because it constantly triggers the display refresh. As a consequence the blinking cursor does not blink steadily but more or less randomly.
For a number of keyboard shortcuts see the HP-48GII.
For a comparisn of the HP-38G/39G/40G/48XX/49G see this overview.
Daily practical use of the HP-49g+ revealed that it is quite battery consuming, even when turned off.
