So according to you it's not a tablet, despite it having a touchscreen and apps running on it, and it won't be appealing to iPad owners, despite this crowd being the best one to realize what's incremental about the GamePad possibilities. I think you are wrong on both accounts.
Okay, I'm going to do you a service right now. I'm going to de-program you from whatever crazy you've managed to convince yourself of after the WiiU's E3 showing.
The WiiU gamepad, is, by the very definition of the term, not a tablet:
Tablet computer
A tablet computer, or a tablet, is a mobile computer,
or
A general-purpose computer contained in a single panel.
Not only is it not a tablet because it merely stream computational data from another device, and can only do so across so many rooms and not outside, but even if in a world where we get to make up the definitions of words to fit crazy agenda, the WiiU pad wouldnt even be the entry level cheapest route into this market for any family.
There are countless budget tablet devices out there, from $60 to $80, with webcams in, running on Android 2.3, out now. Second hand market wise, theres two iterations of iPads now at cut prices, and theres even some market convergence going on with stuff like the Galaxy Note phone being a "phablet". All of these devices with multi-touch. Some now even with styluses, and Wacom digitiser ones at that!
Theres no way to spin this as Nintendo entering the tablet market. That is an intellectual dead end. You can go the living room/bedroom streaming device route of persuasion, but the WiiU pad is in no way a tablet and Nintendo would never advertise it as such so as to not create a fucking PR meltdown the second someone walks out of there house with the thing and the screen goes black.
I am doing this de-programming service for free, because I am a concerned citizen that is worried if you can convince yourself the WiiU pad is a 'tablet', it feels like youre months, maybe days away from thinking you have powers of invisibility.
And I just don't want to see that.
