I have a wallet on a separate computer. Mining on PC, wallet on Mac. But you can still cash out to Poloniex and hold it there for a while while you decide when no whether to load a wallet. There is also a soft wallet for Android called coiniomi that is coming some time to iOS. You can store a wide variety of cryptos there, but it is still a hosted wallet and you won't have the private keys, so I am using the client and I have backed up the wallet.
