One question though.
If I have a wallet on another PC and use another one on another PC. Is it still the same wallet account
that I can or or is it a new one? coz, it'l be more easy if you can see your transaction history using same
wallet account on both PC's.
sorry for my english.
I guess technically if you copy the wallet.dat file between computers it would work.
I haven't tried it yet. If doing that, I would suggest using https://blockchain.info/wallet
as it has the most advanced settings for being an online wallet that I've seen.
[Edit]: Also, if you know the address of the original wallet, you can just track it on the block explorer.https://blockchain.info/address/1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp
You can view this on any computer and see transactions. The wallet would need private keys (originating from the original client, but are able to be exported for other clients or just to be backed up) in order to send bitcoins.
