Only a rumor at this point and $800 seems too low....

The Inquisitr claims that some Apple retailers have already been given price lists for Apple's upcoming laptops and that there are 12 price points ranging from $800 to $3100. Current laptops are said to have only have 8 retail price points: 3 Macbooks (starting at $1099), 3 Macbook Pros and 2 Macbook Airs.

There has been speculation that Apple could be dropping prices of their MacBooks ahead of an economic downturn, though analysts predicted the drop would only go as far as $999 (from $1099)....
