Via an official user account called "The Amazon Kindle team," Amazon has posted a public message to its customers, thanking them for buying more Kindle devices in the last 10 weeks than in the entire previous year. The online retailer thanked those who have purchased the device for their support but also made sure to tout some impressive sales at the same time.

As always, Amazon did not disclose exact sales numbers but it did say it managed to move "millions" of the new device in 73 days, passing the number it sold in all of 2009. These numbers are just for the new Kindle and do not include the older versions. Furthermore, the fourth quarter isn't even over yet, so the sales are likely to keep growing as shoppers make last-minute purchases for the 2010 holiday season.

Here is the full thank you letter:

The Amazon Kindle team says:

Thank you Kindle customers!

Thanks to you, in just the first 73 days of this holiday quarter, we've already sold millions of our all-new Kindles with the latest E Ink Pearl display. In fact, in the last 73 days, readers have purchased more Kindles than we sold during all of 2009. We're grateful for and energized by the overwhelming customer response.

Thank you for being a customer,

The Kindle Team
