iPad's iFad niche has gone
Apple never knew how to do personal assistance and Now that Google's voice recognition, collaboration, security, productivity, Maps, Search, Browser, Social .... Apps are better, along comes Intel with efficient chips that don't burn your lap, don't make you plug in your laptop for a full day and don't make you attempt to type on a kluged up keyboard, Apple's laptops, Samsung's laptops, Google's Chromebooks, Lenovo's PC's, HP's PC's will all outsell iPads.
Once Intel started building chips that do not offend user sensibilities iPad's niche was gone. Moreover, iThings were crippled by their lack of personal context, AI/big-data context, and plays-well-with-others cloud-features. IBM can supply those features, so can MS, Google and other's who have building an open, thin-client heaven, while Apple's ecology has been taking Candy from babies.
