<p>Yes you will be able to access the same coins with both devices. You can think about it like if you make a copy of a key to your home, and give it to someone; both people will be able to open the same door. </p>

Note that the wallet software needs to be designed to handle this.  Some wallets might get confused by transactions that spend their coins that come from somewhere else.

@NateEldredge Which wallets don't check the utxo to determine a users "balance"? Are there some that just store it in local memory until the device issues a new transaction? Seems like a bad idea.

Well, for instance, if you have keys in two wallets, you might accidentally double spend.  As I recall from some tests, Bitcoin Core gets confused when this happens, as it refuses to give up on its own transaction even after a conflicting transaction has many confirmations.  You have to `-zapwallettxs` and rescan to fix it.

<p>Bitcoin Wallet uses a deterministic key derivation, so you are able to use both copies in parallel and see the same balances in either.</p>

Keys/addresses won't diverge. Actually Bitcoin Wallet was the second deterministic wallet, the first being Electrum.
