Google officially launched Google Wallet yesterday.  At this time, only Sprint Nexus S users have access to Wallet.  This will come as an automatic update (no apps to download)  and those who use it before the end of the year will earn a $10 credit.  This limited availability is a good place to start as often with new technology, there are many bugs to work out, businesses to collaborate with, and loose ends to tie up.  Right now, only MasterCard and google pre-paid cards are working with Wallet, but in time this list should broaden. 

Has anyone used it yet?
