[citation][nom]GreaseMonkey_62[/nom]It sounds more like you're talking about iPads - incremental spec changes, no new features (Retina display = meh) and no innovation. The thing is nearly the same as when it first came out. Android tablets - pen input for writing, keyboard docks with USB and extra batteries, microSD slots for storage, HDMI output. And Apple didn't created the marketspace, Microsoft did years earlier, but failed to make it work. Apple made it work for consumers.[/citation]
#1. First to market != creating a market space.
I can create a flying car and sell 2 units and lose millions. Hyundai can make a flying car that millions of people buy, make billions and cause a dozen automotive makers to enter the market and try to replicate their product. They created the market space.
Windows tablets were nothing like what the iPad brought that's why they were a complete failure and no one bought them. iPad created the viable market space for tablets that was never seen before and causes almost every computer maker to come out with one.
HDMI outputs exist with the iPad. Bluetooth keyboards exist for the iPad.
What you mention are the very small changes, the major innovation of a touch only tablet was done by Apple. Adding ultra high res screen was also done by Apple. Manufacturers are copying the single body, embedded battery of Apple not going to easily replaceable batteries.
Apple has done very little innovation in the past few years as has Android manufacturers. But there is no questioning it was Apple that made this market space and brought the major innovation for tablets.
