Note: While the last "balance" is the accurate number of bitcoins available to this address, it is likely not the balance available to this person. Every time a transaction is sent, some bitcoins are usually sent back to yourself at a new address (not included in the Bitcoin UI), which makes the balance of a single address misleading. See the wiki for more info on transactions.
