I have about 20 lists (maybe a little bit of an exageration) within evernote that I use for just this sort of thing. Things to do/try if I ever make it back to NYC, or random gifts to buy for my family/friends for birthdays that aren't anytime soon.
I keep them in related notebooks.
+Self Lust List (Just for random cool things I want, but won't buy)
It works very well. I collect it once, know it will be there if ever I need it again.
