I sort of get what you mean, there is no defined role for the GamePad but like with the DS/3DS, it will ultimately be up to the developer on how they wish to or if they want to implement it.

Truthfully, the second screen only appeals to the hardest of hardcore gamers that want to use it for map, item functions and things of that nature. The larger more casual hardcore gamer, might not actually care at first but if certain games approach it well, it will catch on, although only for single player or online gaming. The biggest draws the gamepad offers will be determined on how it interacts with other tech, such as social media feeds and MiiVerse while gamers are playing or the implementation of the Nintendo TVii function which appeals to the tech toy lover in most people by giving them something new to pull up their Netflix or DVR recording without interrupting the TV screen until they are ready to activate it or having a smaller screen to watch while others are enjoying something else.

As a game playing device, the GamePad is somewhat limited in how it can appeal to a more traditional gaming culture raised on modern classics, due to it being suplemental to most gaming experiences but that doesn't mean it can't improve them down the way. Had the DS not been designed as it was, the recent revival of adventure games on the system via Phoenix Wright and Professor Layton may not have occurred. This device might give way for another boost to that genre or create another one.

All of Nintendo's recent, very successful, systems have exhibited this schizophrenia. Are you supposed to play a DS game with the gamepad or with the stylus? Is the wiimote a motion wand, an NES gamepad, or a Gamecube controller that's been split in half?

The answer is: Depends.

Versatility is the point of all three controllers, and versatility between augmenting a TV experience or providing a portable experience when the TV is busy is the whole point of the Wii U.

Complete BS statement.

Gamepad is just as comfortable, with the same buttons and features. At this time I have zero interest in buying a pro controller and will game mostly with gamepad (where screen is utilized) or wiimote/nunchuk where it makes more sense.

In fact, the one reason why I might by a procontroller as I'm betting VC games that need a classic controller will also use pro at somepoint and that would be simpiler than having a wiimote in my lap with a classic in hand.

Nintendo made the pro controller for the specific reason stated in the post you quoted along with the ability to please a small number of users who fear change. Which is odd as the gamepad has the exact same layout of buttons.

I disagree but I guess we can only wait and see.

1.  How many games have you played with the Gamepad?  Play Mario Chase, Metroid Blast, Zombi U, Rayman Legends' multiplayer, or Balloon Trip, and you'll get the difference very very quickly.  Even with games using the TV, the tablet is often useful for various purposes.  In particular, it opens up new styles of multiplayer gaming that couldn't be done with other controllers.

2.  Nintendo also made a classic controller for the Wii.  Was that because of a lack of confidence in the Wii-mote?  Clearly not.  Not every game will be ideal for the Gamepad.  Black Ops 2 multiplayer mode certainly won't be (since you can only use 1 gamepad) and VC games which make no use of the screen may make more sense with a CCPro.  

3.  The idea that no hardcore gamer is going to use the pad for a seriously intense game is simply BS.  I got a chance to play Mass Effect 3 with the gamepad, and it made a substantial improvement.  In the X-Box 360 version, I paused the game every 3-4 seconds to activate an ability through my power wheel (vanguard playthrough if you're wondering).  With the Wii U Gamepad in hand, I paused the game to bring up my power wheel one time and that was only to see if I could.  The game flowed more naturally and was vastly improved.  Not improved enough to spend another 60 dollars on ME3, but if I had a choice on whether I wanted to play the game with a Gamepad or a 360 controller, I'd pick the Gamepad every time.  And this is a port, not a game designed for the Gamepad in particular.  Zombi U would be borderline unplayable with a 360 controller.

4. Shoulder buttons not being triggers is not a bad thing.  Back in the day, Melee players would actually mod their controllers so that they didn't function as triggers.  Having triggers as opposed to buttons is really only useful in a narrow range of games, most notably racer.  Honestly, how often did you really use that feature?

5.  The shape of the Gamepad is quite comfy.  The design makes it very easy to hold all four shoulder buttons at the same time, something I cant' do comfortably with the 360 or PS3 controller.  

6.  "In order to freely touch any location on screen the user must let go with one of their hands; a huge no no for action games. Holding the device and using both buttons and the screen is just impossible."

Absolutely not true.  It's  very easy to hold the controller in two hands and shift either of your thumbs over to the edge of the touch screen.  This was very comfortable in Mass Effect 3, and in Zombi U having your flashlight on a dedicated touch button rather than taking up a physical button is a subtle but very important enhancement.

Unless you have the tiniest hands in the world, touching the screen without releasing one of your hands is easy.

For the most part, I agree with what you said.
