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 recently acquired a Tab 3. I loaded the blockchain.info app on there and created a wallet. I'm finding it to be VERY useful for daily transactions. I wouldn't feel comfortable storing a large amount of bitcoins that way, but it's extremely convenient for smaller amounts that I want to have with me while I'm out and about.
I use a 3 stage system for my personal bitcoins.
Stage 1
Paper wallet.
Generated paper wallet addresses offline. Sent bitcoins that I don't expect to need access to for at least a month there for long term storage.
Stage 2
Desktop wallet.
Installed Bitcoin-Qt on my desktop. Store bitcoins that I expect to access during the next 30 days here.
Stage 3.
Blockchain.info app on Tab 3
Anytime I feel that I've got less in here than I'd like to have quick access to, I send a bitcoin or two from my Bitcoin-Qt.
