Worth updating?

[BarryMead]

There are a few other options besides waiting for shipping. You could add a flashing port (Harald Pott's USB jack or Marcus von Cube's 2.5mm headphone jack) or your could build a "pogo pin" flashing cable of your own (to flash through the existing port under the back cover). With any of these options you would be able to update the firmware whenever it suits you, and you also gain the ability to upload/download programs and data between your calculator and the computer based emulator. Many members of the forum enjoy being able to try out alternate firmware variations, once they have created this local flashing capability.
