When big gaming sites like Kotaku, Eurogamer, IGN, Polygon, CNET are all going 'yeah, you might want to wait this one out for a bit', i'd say that Nintendo certainly didn't hit a home-run in terms of day-one excitement and value. It certainly isn't blowing reviewers away.
That doesn't mean that it isn't going to sell great or be great when the games come out, but let's at least be honest in saying that most of the gaming press is pretty middle-of-the-road on the thing right now.
It's like saying GAF isn't blown away by Switch's value, because you wrote this post. Ask me as a GAF representer and I'll tell you otherwise. These sites are made of people with different opinions. I saw the IGN video podcast this week and the staff was positive about the Switch. I saw the eurogamer video with the 2 completely different opinions about the Switch. And then there's all the reviews from Gamerevolution, The Verge, The Time, The Guardian, etc. which are hype.
They only had one game or so to test. No matter how GOTY it is, no matter how many indie games are coming, or 1st parties, it's reasonable for sole to recommend waiting. Wii U was a failure so that makes sense. As Gameblog reviewer said, it "feels" like planets are aligning, and that gamers have the desire to cole back to Nintendo with this system.
The more passionate reviewers want to see that happen. Collectively we can make it happen, the more successful it will be, the more games will come, and it will eventually increase value. So us early adopters are important. Waiting is good, we don't all need to be early adopters, as long as we are enough to initiate the virtuous circle.
