I myself use 3 different wallets. One is on my Android device, one on my desktop PC and one online.

The one i like the most is on my desktop, MultiBit. I like it because you can quicky generate new deposit adresses and keep track of your incomes and outcomes. I only use Blockchain for some payments, and on my mobile phone i have MyCelium wallet, which i use for mobile/QR code scanning payments.

What wallets do you use and which one do you prefer and why?
