HP49 is faster and more efficient than HP48 G series calculators.
Many functions are similar to the ones of HP48 and many others was implemented,
like symbolic matrixes and new features in 3D plots.
However, many HP48 users will not like to leave their old HP48 calculator.
It is believed that greatest part of HP48 users will buy a new HP49 without stop using HP48.

4 - What is VGER?
HP calculators have codenames, usually used during the development.
HP48SX codename is Charlemagne, Alcuin is the HP48G codename and VGER is the HP49 condename. The name VGER comes from the Star Trek first long shot, that was produced in the later 70's.
VGER or V'GER is the contraction of the word "Voyager".
Tells the motion picture that the space probe Voyager VI, built by NASA, in the later 20th century, had fallen into a black hole and emerged on the other side of the Galaxy, near a planet of living machines.
The inhabitants of the machine planet found Voyager VI and gave it the ability to carry out what they believed to be Voyager's mission: to collect data and learn all that is learnable, and to return that knowledge to its creator. When returned to Earth Vger joined with Will Decker and Ilia, beginning a new kind of being.

HP development teams give names to calculator during the development stage.
The codename given to HP49 was VGER, and it is the name that appears in the HP49 Easter Egg. Maybe because members of HP49 development
team are Star Trek fans.

It is supposed that there are 7 main reasons for not to make a calculator with IR:

1 - IR becomes the calculator more expensive
2 - IR demands more time during the assembly service
3 - IR was not included in order to give space to FlashROM
4 - many schools dont permit IR calculators in tests alleging IR transfers can be used to cheat in tests.
