What sort of odometers do folks prefer, if any, while touring?

I am sure preferences differ, but following is my feature list of what I like in an odometer:
[Must have] - distance, either elapsed or trip, but some way of seeing how far I've gone
[Important] - either excellent battery life or easy to recharge, km and miles,
[Nice] - altitude gained/lost, gps tracks to record trip, current speed, average speed, max speed, wireless
[Not important] - cadence, heart rate, timer, temperature, clock, riding time, etc.

I've used a variety of odometers over the years, starting 30+ years ago with mechanical ones with small rubber band drive, to the first electronic ones, to an avocet 50 (altitude!), to a variety of wired odometers (ripped cables/argh!), to more recently Garmin 500 and Ultega wireless. The latter I liked a lot but doesn't seem to be available anymore. Garmin 500 is ok on the feature list, but battery life is serious drawback if I'm traveling w/o as many opportunities to recharge.

My Ultega isn't doing as well anymore, anyone know of something similar: Amazon.com : Ultega Wireless All-Round Bike Computer : Sports & Outdoors
