Cool. I think I'm addicted to apps really shouldn't be downloading more but I can't help myself. I ought to be deleting not adding
Dude, at least you only have one OS in your household.
I have WP, Windows 8, iOS and Android and waaaaaay to many apps to keep track of, some I would get on this specials just because I own em on other OS's and no other reason as I rarely ever load em on other devices than the one bought for.
Edit: one of biggest wishes (Something I know will never ever happen) is for a store where you buy apps and then own/download them for any OS. Then again looking at Humble Bundles, it must be do-able. As you get codes to enter on Ubuntu and Steam stores for apps on its sales, they can just add one for iOS....
