While Sergio has had a couple bad arguments in this thread, if this is true--I can't verify it because blockchain.info does not display the extra nonce and I don't see a raw copy link anymore--this would certainly have strong implications that satoshi indeed had the resources to mine 50BTC/~13min throughout the difficulty 1 period. 70 minutes passed between blocks 1-10. lol @ 14kh/s between blocks 0 and 1, that's obviously satoshi trying his hardest to mine for a week rather than him waiting for public release before mining.
Use blockexplorer.com. It shows the coinbase script. The last bytes are the extranonce:
e.g. : "coinbase":"04ffff001d0104"
then the extra-nonce is 04.
Regarding the speed of a computer in 2009, my computer was almost as fast as Satoshi's. A Core 2 Duo. And because it has two cores, it can run two mining threads.
Why does gmaxwell says such an erroneous fact about hashing rate in 2009 ? Maybe he had a Commodore 64 back in 2009.

The CPU is a Intel Core 2 1.83 GHz. The performance is 3.4 MHash/sec (111 MiB/sec)
So who's making FUD ?
