The 75% disapproval of a 6" phone in the AC poll is huge in my opinion.
I'd have to believe Google is fully aware a 5.9 inch device isn't going to sell as well or in as high a volume as a 5 inch device does... a Phablet is a specialized market but at the same time a growing market dominated by Samsung for the most part.... the 75% disapproval on AC is interesting.... I looked around at several different sites who also have polls and seen anywhere from 55 (against) 45 (For) to 75 - 25......
I think a 5.9 inch Nexus will sell pretty good.... Not 10 million the first weekend good but I'd venture to guess they will be "Sold Out" within a few hours of launch.... Granted "Sold out" could just be 10,000 devices depending on what Google estimates and puts up front orders for.....
