pro controller looks pretty good

I'm not sure what you mean by "gaming for game design."  Did the manufacturer of your laptop advertise that funtion heavily as one of the primary features in order to sell more units even though it's not one of the core functions?  Then, yes, it's a gimmick.

So what?

The word gimmick has become such a buzzword lol.

Gimmick isn't an inherently negative term but sadly people only seem to use it negatively. Personally, I think we need to learn more about the Switch before we can come to both positive or negative conclusions. The people already claiming it's gonna fail need to just let more news develop so we can breathe and observe the console. But there's nothing wrong with discussion or predictions discussing the console of course.

On these forums, at least, refering to something as a gimmick is akin to insulting a family member.  It doesn't make any sense, considering "gimmick" doesn't refer to value. 

"[In response to being asked if his band does gimmicks] Gimmicks, here we go again, gimmicks man, I'm tired of people saying we're.... gimmicks, what is this? The world is nothing but a big gimmick, isn't it? Wars, napalm bombs, all that, people getting burned up on tv and it's nothing but a stunt. Gimmick. Yes, we do."

-- Jimi Hendrix

Seeing that amazing quote made me remember that I was supposed to finally check out Jimi Hendrix's discography. 

Thank you for that.

sorry, gimmick for game design :p

Maybe because is intentionally used with that negative connotation like 9 out 10 times?

I agree, though there are still things I am uncertain about..

Where is the gimmick again? There is nothing new or unwieldy about this tablet.
