I was thinking about purchasing a Tablet (Perhaps the Samsung Tab 3) from Sprint since I already have Sprint with my smartphone. Can I download a wallet onto a tablet? How safe is it to use something like Coinbase or the other exchanges with the Android Operating System on a Samsung tablet or smartphone? Should I just stick to my Gateway laptop, or home desktop Windows computer?
I'd say safe to keep small amounts of coin that you're not worried about losing, but ultimately having all your bitcoins directly on a a phone/tablet is crazy, you're better off using something like blockchain.info which is a cloud wallet of sorts but still has an android app even if it's a bit basic.
