Who is this thing for, then? The average consumer expects and uses all of these missing features. You know, people who bought those things you listed.
This device seems to be targeted to people who want to play Nintendo games and do absolutely nothing else. That's a damn small market.
I'm sure the vast majority of the average consumer owns many devices on which they can run apps such as Netflix etc, people who currently have subscriptions are already accessing content just fine. Having video streaming services would be a bonus for the switch, but a large number of people already own devices which are more than capable.
I use my consoles to primarily play video games. We have android boxes in our household for anything else, and iPad and mobile phones in addition to two laptops. The Switch not offering video streaming has 0 bearing on me, personally. I'm sure the majority of GAF with subscriptions also own multiples of the listed devices.
Issues regarding using an App to voice chat and set up parties are legitimate points of contention when it comes to the Nintendo Switch. However seeing threads complaining about missing charging docks (the xone came with batteries, the ps4 with a 30 cm charging cable which made it impossible to play with whilst charging), missing a optical out port alongside this are quite tedious to see.
Again I repeat, there are currently major issues with the switch - all of which (imho) surround the online offerings.
Personally, I only ever purchase xbox live gold when my brother or myself are in the mood for halo. I purchased ps+ for TF2 and BF1 yet the majority of my online play the past few months has been overwatch on PC and will continue to be so. I'm curious to see if nintendo offers a (I should hope) cheap alternative to it's competitors however I will not be purchasing a membership for reasons well documented on GAF.
- As you've stated the average consumer purchased the devices I listed for video streaming services, so I don't see why a games console releasing without would deter them.
