The only reason not to include mobile 4G/3G is to cut costs.

No mobile data, severely underclocked hardware, low 720P screen.

If you can't upgrade the battery, then I would hope the device is water proof.
And if it isn't water proof, then it is a stupid design decision, lithium battery's have a finite life-span, it is a matter of *when* they fail, not if.

I honestly can not believe you are using 3DS and Vita as the example here. PSP and DS sold nearly 250M devices by being leaders in the mobile elctronics world. Vita and 3DS have sold not even sold 1/3 of that, thanks to the lack of evolving with the times. Now, than with this blunder, I will be surprised if Switch can make it to 30 million units. Console and handhelds are not impervious to changing market. If they continue don't grow, and stay competitive with the competition (PC, Laptops, Tablets, Set Top Boxes, Smart TV, Smartphones) then they will become unsustainable.

If they are lacking the basic applications (Web Browser, Netflix, Hulu, Music, Photos, etc.) then I will be completely :S

Easier solution, continue to use my 3G Vita, because it appears mobile/handheld tech decided to come to a dead stop, and then proceed to reverse over the last five years. It blows me away that my Phone from 5 years ago is still a more versitle, and entertaining device than the latest Xperia I had.

Yes, and it remains the best mobile device ever made. Unfortunatly, Sony decided to cease support and seriously gimp it, in order focus its efforts on the Xperia Google Phone line instead. To the tune to over 3 billion in losses in the years since to top it off. Had they released constant updates to the Vita, including 4G model, and a full fledged phone model, perhapps, we would actually have some options in the mobile industry instead of the current dead end douply we have right now. And, we might have some actual mass market games coming to mobile, instead of the great but niche titles we have right now.

Of Course I use 3DS/Vita like examples because they are last handhelds. 3DS/Vita sold less than DS/PSP because today everyone can play games on every phone/tablet and that wasn't case in DS/PSP era, not because handhelds didn't evoloved with times. 3DS/Vita and espacily Switch are also evolving, you will have internet browser, YouTube, Hulu or something similar...but not having 3G/LTE is not deal braker in any case for market, becuse people still look at Switch for games on 1st plays not for 3G/LTE, Switch is still gaming deviace on 1st place not phone or tablet. And if mobile internet is so important for someone it could easily use hotspot from phone. So it not really big deal in any case like you want to sound.

Sony cease support because nobody really wanted 3G/LTE Vita and beacuse model without 3G/LTE was incomparible more popular.

Deviace certainly is not waterproof because it has active cooling and holes for cooling. Today more and more phones have non removable batteries, so it doesn't seems like big problem.

Exactly the problem with Vita and 3DS. 

1. Most are not connected devices, so why take them out on the regular.

2. Thanks to number one, they are regulated to basically dedicated gaming machines.

3. Due to one and two, this is the smallest handheld generation ever, and therefore finding someone with a Vita or 3DS is a 1 in a million chance.

Not everyone is so lucky. Nor do I have the room to carry multiple devices everywhere every day, or the time to be pairing them. As for the battery, it really depends on how unchangable it is. If I can get to it to swap it, then cool, I typically have power around me all the time, but as mentioned below, batteries only last so long.

So much good stuff here. It is really incredible that they won't offer a wifi one for $299.99 and a 4G one for $399.99. I can live with paying $399.99 for something I will use for a couple hours everyday. But, even at $250 or $300, it is hard to justfiy for something I will only use once in a blue moon. The underclocked hardware and low res screen where also something I could live with for a great mobile device, but now that it appears it will be an at home only device, it fells quite upsetting. 

The battery thing I have to see. If it is soldered into the mother board, then that is just....?

Well I'm guessing that if people have the money to pay another data bill just for a  handheld console, they have the money to pay a mobile hostpot or unlimited data. And you can use those options for more devices, not just for the switch. Time to pair the device? You have time to play outside but you don't have 30 seconds to pair the switch to an external online connection?

Mobile hostpost, wifi carriers and free wifi everywhere... yeah I don't see the need of a more expensive device AND another data bill just for the switch when the internet is so accessible these days. 

I feel like this is something only you care about

Love when people make themselves look deeply disappointed about the lack of something nobody was expecting anyways.

The thought that people really want a 3/4/5g model and are actually willing to pay for it is disturbing. Where the hell were you when my precious Vita was failing? Just hook it up to your phone via wireless hotspot and move along. And don't act like you cannot do it... because if you could pay for this feature, you can do it with your phone.

Truth is, this feature is not necessary and will have very little measure on the success of Switch. I guess a few people will be upset because Switch will not offer every feature known to man ever (I was very mad it would not mow my lawn... shit, I have a huge yard) but I doubt those people matter.

My 13-year-old GBA SP runs just fine! Sure, the battery isn't as strong as it used to be, but I can still squeeze 5-6 hours out of that lil' sucker. Never changed the battery. 

On top of that, I'm sure you will be able to change the battery. It will be just a little more complicated. Just like with the Dual Shock 3 and 4. On paper, you can't change the battery. I did it multiple times though. When a replaceable battery is that important to you, 5 minutes of work with a screwdriver shouldn't be too bad.

About 4G: Sucks for every gamer who still hasn't a smartphone. Both of them. 

I don't care about the 3G .

Maybe the battery could be an issue though. The chance of battery issues is low for Nintendo consoles/handhelds, but still it could happen. We'll see how that goes.
