I think a GPS watch is definitely on the list at some point. I do a fair bit of mountain biking and it would be handy to have.
Unfortunately though all my backpacking kit is about 10/20yrs old so looking to replace a lot of it. Nothing wrong with the gear but by replacing the tent, backpack and sleeping bag I'd easly knock off 4kgs from the base weight. Amazing how light kit is now.
Still it is Christmas and I have been good...
