I had initially downloaded Fandango simply because its popularity causes it to show up on the main Apps page. However, for some reason, Fandango only lists 4 of the theaters in my vicinity, whereas Flixster shows 17 (yeah, there's a lot of movie theaters near me). For that reason, Fandango had to go.
Flixster isn't perfect either, though. For some reason, on Fridays showtimes are never available for any of the 17 said theaters (has this happened to anyone, btw?). Which is the night I'm most likely in need of the app.
I had downloaded Connect4, but between only having 10 games (stupid demo) and continually losing to the computer (damn diagonal!), I ended up erasing it.
Sudoku is hard to use, but since I'm such a fan I've kept it... it's good for the 20-minute train commute I take every weekday. Speed Brain sucks, but it's not a terrible thing to have if you've got a minute to kill, especially with the current lack of games in the App Catalog. So those two I kept.
Haven't found myself erasing too many apps because I'm rather selective about what I download in the first place. I just wish I could get rid of that stupid Nascar app. I'll never use it, and that icon is just an eyesore.
