Amazon is notorious for making sale number claims of its devices while providing no numbers for proof. They're continually allowed by the press to do this without consequence. I say it's about time they put on their big boy pants and release sales figures if they're going to send PR emails like the one AllThingsD says they received.

Amazon claims that Wednesday, the day after Apple revealed details of the iPad mini, was the best day of sales for the Kindle Fire HD. Prove it.

If true, I'd say what it really proves is there are plenty of people out there who'd much rather have an iPad than a Kindle Fire. The only thing stopping them is price. Give it time. Apple will find a way in the coming years to lower the entry price to own an iPad.
