I use omnifocus for task tracking. I used rememberthemilk for awhile, but the lack of projects/taskgroups pushed me over the edge. Omnifocus has enough features to make me want to poke my eye out, but they've done a decent job at keeping the interface clean. I've even been using it for issue tracking lately. For actual stuff organization, I throw things in random bins and photograph/track them in Evernote (i.e. your scissors are in Bin J). I've tried the whole "keep related things in related bins" thing, but the space/time complexity to resize the various bins when they get full is way beyond polynomial time. Whereas sorting and tracking randomly has O(1) lookup and O(n) resize (and resizes are rarely necessary).
