I should have clarified; yes indeed, Silk does perform like a pig currently, but I like the idea behind it, and I believe that Amazon has the engineering chops to pull it off.
Immediate access to the mobile phone market along with a huge amount of data that can go Amazon's way if they fix Silk, might make a partnership seem mutually beneficial. (Also, since the mobile phone market is still carrier dependent, Amazon will have a harder time penetrating that market segment on its own)
