The tablet is an inventory box for games.

I wanted to stop reading after that too.  Because Nintendo Wii U GamePad has been the single greatest success For Me in MY life.  But i did't top reading... and all i can say is I wish i had.  I'm happy with Iwata's decisions as they affect me.  I don't want Yoshi's fruit cart touch games.  The Nintendo Wii U GamePad serves it's purpose perfectly.  Hardware and software are in harmony.

Removed the haterade from this sentence.  You failed to mention it serves a million non-game functions..  kinda useful these days.

I know it can do more, but in most non-nintendo games it is an inventory box.

"It serves a minimal function in most games, adds a huge cost in development, increases the price of the system for consumers"

I stopped reading after that.

The "adds huge cost in development" bit is complete bullshit, but the other 2 seem pretty bang on.

i'm also saying it's mostly an inventory system, a very good one.  I don't want it to do touchscreen gameplay.  The Nintendo Wii U GamePad has a million non-gameplay functions.  That's the true beauty of it.  

I don't see how you can say hardware and software are in harmony.

Look at some of the best selling games on Wii:

Wii Sports/Resort - Used motion to bring sports to life in a game

Mario Kart Wii - Use motion to simulate using a steering wheel

Just Dance, Wii Play, Zumba, Mario and Sonic, Crossbow training, Skyward Sword, Sports Active, Mario Party  etc. all RELIED on the unique Wiimote. Sure there were some other games (Smash, Galaxy) that had more traditional control methods, but these make up the minority of the top 30 Wii software. There is a clear harmony between hardware and software.

Now look at the best selling games on Wii U:

NSMBU - Gamepad used in one mode of the game

3D World - A few added gamepad features

LCU - A few mostly awkward features

Pikmin 3 - Map

Wind Waker - Inventory

Zombi U - Good use of the gamepad

Just Dance - One forgettable mode for non-dancers

MH, COD, AC, Sega and All Stars etc. have no major reliance on the gamepad. There is a clear disconnect between the software and the major selling feature of the hardware.

From a sales vs hardware-dependent-gameplay perspective, like you suggest, you are correct.  But for my purposes there is perfect harmony.

 I like the ease of inventory systems

i like using internet browser all day

i like typing to friends 

i like playing off tv

i like controlling my tv

i like selecting my game with a single touch

From your perspective there is dissonance because a correlation between hardware and gameplay is more important to you than hardware and versatility or simplicity..  I don't believe a touchscreen can improve gameplay much further than it has on Wii U and it's already raised gameplay as high as it needs to go.  I like my games the way they are. That doesn't mean the Nintendo Wii U GamePad shouldn't exist though.. there is so much to gain from it.. like the things i quickly listed above.. they are not simple or possible on other systems.  

If it doesnt do touch screen gameplay, its lost its non-gamer or even casual appeal.
