>I said "Get over it" so that makes me correct
No, seriously. I barely want to muster the energy to address this.
Let's start with the obvious. You are comparing a low quality chinese knockoff tablet (it has bricking issues) to a mass market American device. This is like comparing the costs of a Dualshock knockoff from Dealextreme to a Wii remote from Bestbuy to argue that Wii remotes are more expensive. If you want to compare it to anything, compare it to an actual tablet on the western mass market. Better yet, compare it to an actual controller sold in stores. The market for knockoffs, and the market for high quality products from an established company is very different.
Second off, the ePad is missing more than those 3 features from it's spec list. Rumble, gyro, magnetometer, and video streaming hardware to be exact.
Third, nobody but you expects android running chinese Wii U knockoff tablets. Nintendo would never let anyone get away with that. They would have to reverse engineer exactly how the Wii U video streaming works, and then dodge lawsuits.
"Get over it". You chucklefuck.
Edit: Not to mention the controllers being expensive bit sort of comes from Nintendo themselves. We didn't make it up.
