What you don't have that I would miss
- Screen Filter
- Flipboard
- games/books/drawing apps/learning apps for your kids
- games for yourself
- music apps: cbc music, rdio & tunein radio for me
- off line reader: pocket or similar
- weather app
- justpictures. A flickr/picasa/facebook/many more picture viewing app. Provides notifications when people have uploaded new pictures, which is its killer feature.
- mx player
- aldiko/fbreader for reading books outside of the kindle walled garden
- atm locater app
- qrcode scanner, which is mostly used for installing apps from outside the store
- good calculator (droid48 for me)
- connectbot (ssh)
- good alarm app (double twist for me)
- skype, voip app (I use Bria)
- shared grocery lists: our groceries. indispensable.
- todo app (i use got to do)
gimmicky apps that are worth installing if you have lots of room: (granted, I paid 10cents for much of these)
- star chart
- sound hound or similar
- flight track
- camera app a la instagram (camera zoom fx, paper camera)
And that's just what's on my front screen. There are more, but most could be easily uninstalled.
p.s. how do you format lists on HN?
