1) the Switch unit is smaller than the gamepad (which is a truly sad commentary on the Gamepad)

2) the Switch has two other means of controlling it when not using it for off tv play that are not bulky at all that came bundled in, the Wii U did not.

3) the GamePad was bulky for no adequate reason, here the size is a trade off for the specs they are achieving.  Making it any thinner would limit the chipset, remove the fan, limit the clock speed, and limit how much they could augment the Tegra in the system.  Shrinking the GamePad would have cost us...a front facing camera and speaker size.  Yeah, not an even exchange.  

1) Soundwave was not saying that it would fit in his pocket, he's saying that no one puts their handhelds in their pockets cause that long ago became a bad idea.

2) No, I say the Switch has a fan because it has a fan vent on top that can plainly be seen in the reveal trailer and in this live demonstration:

And also because the Switch is just within the thickness range needed for a fan to fit.  It's only a bit thinner than the base/keyboard portion of the thinnes ASUS gaming laptops.  Take away the space needed for the keyboard (the Switch doesn't have one obviously) and bam, you are pretty dang close to the Switch's thickness.  Besides, an internal fan is crucial to getting the most out of a system and getting consistent performance while controlling heat.  A fan in the dock would be a neat supplement but it would not be an adequate replacement for an internal fan.  I've been saying the device itself has a fan inside since the reveal, regardless of what the dock has.

Imagine, USB type-C, Quick charge, 3DS style battery life, GC VC games, built in web browser like with the 3DS and Wii U.

Or even better (subjectively) OLED.

OLED has lower power consumption and has faster pixel response (think ten times faster than high end TN panels, forty times faster than good IPS).

Yea OLED would be fantastic! I have a Galaxy S7 and after owning Samsung phones for so long with their Super AMOLED displays, its always so hard to go back to anything but OLEDs @_@

I wanted to buy an OLED monitor for my PC for so long but alas, not there yet T_T

1) Oh. I thought he was saying it was too big to fit in his pocket. I mean, plenty of people still put their 3DS in their pocket (at least around me they do because I still street pass with a lot of people) so I guess I misunderstood.

2) I completely agree with everything you said here. I simply do not think the dock has a fan (there seemed to be no signs of one based on the picture). I think the console itself does but the dock does not for every reason you listed. Other than that small difference, I agree with you.

There's two fans. One is in the system. One is in the dock which provides additional cooling. You're not going to see the fan inside the dock because it's inside the dock. 

Laura Kate reported that and she's basically been right on everything regard the Switch (segmented d-pad, swappable sides, trailer reveal date, etc. etc. etc.). 

You can see two air intake vents on the bottom back side of the unit right there anyway. That's likely where the dock fan pushes cool air into.
