Strong December sales of Amazon's Kindle Fire tablet are potentially eating into Apple's share of the Christmas market, with Morgan Keegan analyst Tavis McCourt reducing his Q4 iPad sales estimate from 16m to 13m. Amazon has not provided an exact Kindle Fire sales figure, only confirming that it has sold 4m Kindle devices during December. While that figure places the Kindle Fire's probable sales some way behind Apple, the tablet appears to be slowly catching up with its high-end rival.
