Honestly, aside from the always entertaining (or not) apple-android-PC flamewars, the problem is that the industry has kinda plateaued, where the newest developments are more enhancements than true innovations. Ok, so the whole touchscreen phone and tablet thing had been done in the past in various forms, so the iPad and iPhone weren't truly new, but they were the first ones to have real broad appeal thanks to apple's shrewd marketing.
Now, it's just enhancements to the iPod Nano 9th generation, or iPhone 5s, or iPad Air (aka 5th generation).
