After slogging through quite a few pages of discussions about firmware, fireware updates, pros and cons of updatable firmware etc. I can tell you the secret.
If it comes with upgradeable firmware, that is good and bad. Good because they can fix it. Bad because they might send it out defective.
I've been watching this for years with video games. before every game console was hooked to the internet, game developers actually finished games before shipping them off to be sold. Now they just get the game playable, send it off to be made into discs, (to meet deadlines and release dates) and spend the next two months feverishly polishing the game. You cheerfully buy the game, pop it into the console and are faced with..."The day one update!!!"
Relax. It's the future of electronics. In twenty years, we will probably be talking to our PV's instead of pushing buttons. in less than two years I bet we get touch screen or at least touch sensitive mods.*
EDIT: *I have been informed that touch sensitive mods already exist.
