An excerpt from the source Forrester report
While some may view a partnership with Google as an asset, we see it as a challenge. Product strategists that we’ve spoken with at OEMs have voiced frustration about the limits of Android — its lack of polish, the terrible shopping experience in the Android Market, the rules that Google has set for Honeycomb use that limit differentiation, and the fragmentation of earlier versions of the OS. Only 9% of consumers considering buying a tablet actively prefer an Android tablet — compared with 16% who prefer iOS and 46% who prefer Windows. Barnes & Noble has chosen to emphasize its own brand and user experience on the Nook Color rather than emphasize the Google or Android brands, even though the Nook is built on Android. Amazon may not wish to go that far on the curation spectrum, but it does need to differentiate its flavor of Android from all the rest, and that may come from emphasizing the Amazon experience over the Google one.
