Lucky you, I would never keep a phone for more than a year. In two years' tim ecome back here and tell us how much worse the battery life is. If you can notice it at all it will mean you got a really bad battery. We are not in the 90s anymore where NiCd and NiMh batteries were used and you had to worry about it all the time. This is 2010 and such stuff is pretty good, lasts a long time and is cheap, so replacing a battery will not be a problem. As for the sany, I would hope to have it for a few years too.
