I'm not saying it will sell well because it has Android and streams PC games. Not at all... I am saying that it can't "bomb" from a user perspective because of that. People say a device is afailure because it is discontinued and software support dies. This is impossible with Nvidia Shield. Games and support will not stop if it sells 10 or 1 million units. 

Secondly, I am not trying to convince anyone of anything. Buy what you like and can afford. I guess don't take in to account that I may have a little more disposable income and that the price of $299 isn't something I would consider as a dealbreaker for a cool gadget.  If someone is able to take their Galaxy S3 they already own and attach a Moga controller and accomplish the same thing and save $250 bucks in the process...power to you! 

All I am saying is that it's an awesome "premium" handheld device that does a LOT of things that no other single device is currently able to do. These features along with it's flexibility and design build/quality make it the best gaming handheld for my gaming needs. 

And for the record, I am not new to the portable handheld game or am someone that hasn't had the chance to use many hence Nvidia shield is easily blowing me away. I have owned or currently own Game gear, all kinds of gameboys, Sega Nomad, GP2X, PSP, DS, and PS Vita. 3DS I tend borrow from my little sister hence I didn't need to buy one myself. 

While I agree with you somewhat because it does sound like a cool device, It can't play Gravity Rush, Uncharted, Person 4G, Kid Icarus, Castlevania: Mirrors of Fate, Batman Blackgate, Hot Shots Golf, VLR, etc etc.  But I can play PC games on my gaming PC or laptop and Android games on my Galaxy or that plug n play thing for TV's...I fail to see how it is the best portable overall.  But it does sound cool.

Who says it sucks? I'm simply saying I cannot see this selling anything close to decent numbers, at all. Whether it's a good product or not is entirely besides the point. Tons of really great products sell extremely bad, and vice versa.

Here is a very detailed Shield review I stumbled upon for those that may be interested - http://www.youtube.com/watch?v=sTOSMQFjcQw&list=UUTzLRZUgelatKZ4nyIKcAbg

This is a very good point. Essentially you are right... If you are buying a portable device for a select few games that are not available anywhere else, all of the points I made in OP are irrelevant.

This really sin't me...not at least when it comes to mobile gaming. When it comes to gaming on the go, I personally just want to be entertained and can't really think of a single show stopper title that I have to play or GTFO. I just want things to do and many games I can play and there is plenty on Nvidia shield in terms of gaming variety to keep someone like me entertained.

Another reason why this device may appeal to someone like me is the fact I always enjoyed tinkering and hacking open source handheld devices. The problem I ran in to before was that the open source devices usually did not have the build quality or community/dev support that was worthwhile. This device however is as well built (if not better) as the 3DS or PSVita and is running open source Android, one of the most supported mobile platforms on the planet.

But yeah...to recap, if you want a device that is resonably priced, and has a list of games you absolutely want and must play, there is a good chance that the Shield isn't the best choice for you.

But if you want a very well built device with top notch specs, that provides a huge variety in terms of types of games you can play, and it offers many extra features plus allows for open source hacking, not to mention a full blown mobile OS...and you are willing to pay a premium for it and other stuff needed to make the most out of this device, Nvidia Shield is the ticket. There really is nothing else like it at the moment.

I wonder if they have one of these up for display at, say, Best Buy? Id love to check one out. Anyone know?

So you've pretty much moved the goalposts so much, that your current stance looks like this: "no matter what happens and how hardly it bombs, Shield is the best handheld ever and is a massive success. Trolololo!"
I get it now, no point arguing over that.

Exactly. Can't argue if its true...

Liked the video. Looks like a cool device. I dont like android as an OS though. If they made a windows 8 version, i'd be all over it(and if it had a bigger screen, 7-9 inch would be preferable. Does it do HDMI out? I didn't watch the whole video. That would be good for travel gaming as you could just hook it up to a tv in your hotel, or if your car has a tv into that. My biggest complaint about mobile gaming is the size of the screens and the controls.

I might have gotten it if I didn't already have a 3DS, I don't have enough pocket space.
