I also got one - ironic because our Keurig is dying and I'm waiting for their Customer Service to reply to an e-mail I sent them the day before the Tassimo showed up. (In another thread I said "file this under "are they reading my e-mails?"".)
I went ahead and registered it for the free boxes of T-discs. If our Keurig doesn't get replaced, I just might move over to the Tassimo, but they don't have so many choices in coffee and they don't look like you can get them as many places or for very good prices.
They definitely make most of their money from the discs not the machines - but I looked it up and the machine is priced at $129.
