I think the IP5 will sell like hot cakes, but what we are seeing here is the same type of rumblings from the blogosphere that took down RIM. People complaining of complacency, the devices looking the same for each generation and no innovation. Whether it's true or not, these guys make or break tech companies, and this is the first sign that people won't continue to blindly call it the best phone available for much longer.
This industry is very cyclical, and maybe they have hit the apex, who knows? It'll take a minimum of 4-5 years for it to pan out if this is what we are seeing.
