In what is another indication of a rumored Amazon tablet, Taiwanese trade publication, DigiTimes, this morning quoted sources from the supply chain who said Amazon has become the second largest buyer of tablet parts as component suppliers are lining up to provide parts for Amazon’s seven- and ten-inch slates. That’s a notable change from previous reports asserting Apple had gobbled up pretty much the entire supply of tablet parts. The Amazon devices are apparently due for a fourth quarter launch and the online retail giant is targeting to ship four million tablet PCs this year.

The publication named suppliers which include an unnamed processor from Nvidia, gravity sensors from Sitronix and touch panels from Wintek (also an Apple supplier) in addition to J Touch and Chunghwa Picture Tubes. Note that the mention of the seven-inch Amazon tablet probably means a new Kindle e-reader while the ten-incher most likely refers to a brand new Android-powered tablet said to be integrated with their cloud stores carrying mobile apps, music, movies, e-books and other digital warez. A Retrevo survey indicated that 79 percent of buyers would consider an Amazon tablet if priced less than $250. Apple is said to be considering cheaper components for next iPad amid the increasing pricing pressure in the market.
