Updatable firmware is a fact of life for most newer consumer electronics.
That is only going to get more prevelent in the near future.
Many folks find this an irritant and confusing but it's actually a good thing.
At least there is now the opportunity for manufacturers to choose to make improvements when issues arise. There have always been issues with consumer electronics and, until the advent of user upgradable firmware, the buyer was stuck with those issues until they replaced the unit with something else.
While many folks here will disagree, I generally stick with the following philosophy when it comes to firmware updates:
I always immediately update the firmware when I buy a new CE device because it will, invariably, be shipped with a very old version.
But, after that...
I never update until the new firmware has been "vetted" by the early adopters (unless I have a critical issue that must be fixed ASAP)
and, maybe, more importantly...
If it ain't broke, I don't "fix" it.
