Closed Bitcoin-QT on pc1 (from where i sent the coins) after 10 seconds
Your client need to broadcast the transaction to your peers and your peers then further relay it to the whole bitcoin network.
So, you should not close your client immediately (or in a few seconds) after creating the transaction.
I now wait until there is at least 1 confirmation before closing QT.
Next time, you can go to blockchain.info, enter your address (the one you send your btc to), and see if you can find that transaction.
If yes, then you are ready to go.
