Instead of raising the price from $399, they should've just put an A14 in. What an odd choice to raise the price to such an uneven number.
They're also fast approaching the point where 2014's iPhone 6 design just isn't going to cut it.
Both $399 and $429 are uneven numbers. And I seriously doubt a $30 price increase is what's causing the lack of demand. I'm not so sure it's the design either, as I see people on this forum all the time talk about liking older iPhones (and Macs) and "why fix what ain't broke" type mentality when it comes to design.
