You have a 1 year warranty against manufacturers defects, as long as you're not smashing the buttons with a hammer or pouring water all over them and you're just normally using them, you should be alright.
How is the gameboy emulator for the Droid? Does it work fairly well? This would be one of the applications I would be looking at if I go ahead and upgrade to the Droid. I have NES, SNES, and Gameboy emulators on my current windows mobile device (great for passing time) and would want to run these on the new phone as well.
the emulator is fantastic. i have read about some lag but i have not seen that yet. maybe when i try to play the bigger games. i am currently playing final fantasy but i have also download a mega load of roms that i hope to get to. i am currently looking for the system that made Donkey Kong (the Original Game). i love that game.
however, as my first post stated, i am worried about the buttons i use for A and B. over time, the wear and tear may be too great. the game boy advance emulator has a directional pad, start and select button that appear on the screen if you want, but no A and B.
the emulators on in the market under games. from gameboy, gameboy advance, NES, sega, etc....
