It'll last. Mine even stays in tune in it's case for long periods if the temperature doesn't fluctuate too much.
One thing I did learn when I had it in Arizona. Taylor doesn't sell many guitars in Arizona because it's very dry and Taylors don't do well in a dry climate. I know that's true of guitars generally, but other brands sell in Az just like in other states. Apparently Taylors are made in a humid environment and that comes in to play. Anyway, if you're going to have it in a dry climate for any length of time, get a humidifier for it.
