Tungsten T3 farewell soon?

It seems like the battery on my Tungsten T3 is starting to fade and drain faster than it used to. I found it at 25% battery after leaving it off the cradle for a couple of days.

I suppose I could do a battery replacement and keep it going for a few more years. It's getting pretty close to 3 years since I've had it (purchased off eBay after my first one got waterlogged) so I'm not sure if there's much point in doing that. I've been using my Cliq more for PIM stuff lately even though it's not perfect and not nearly as good as PalmOS was at that kind of stuff. The Android version of Pimlical is helping with that though.

I'll probably end up letting my T3 retire to the Drawer of Old Gear.
