His points were still legit.
The Switch is a great handheld though. Obviously it cant compete as a home console but its by far the best handheld option you can buy right now (and kind of they only relevant one left). So there is definitly a market for this.
People should also not forget that quality/games and so arnt as important for success but marketing is. While nintendo is so far selling way more switches then wii u, they are also putting alot more money into marketing.
With enough marketing, you can basically sell anything. But marketing is also expensive, so selling less with less marketing can sometimes be better then selling more with tons of marketing.
