As a mobile games developer, I feel that Unity as a game engine has lost its way in the last few years, and the recent acquisitions reflect that. Instead of capitalizing on its merits and strengths - an easy-to-bootstrap multi-platform engine which is perfect for mobile development - Unity has opted to try and compete in the AAA/AAA-like market against Unreal. The recent announcments and the features actually being delivered from Unity support that strategic transition, and this leaves the engine in a state of constant conflict with itself.
Ask anyone who tried to integrate a 3rd party advertisment engine into their game and you'll understand why including a 'default' or an easy-to-bootstrap advertising and user-acquisition tool is a good move. This will hopefully streamline what is nowadays a less than ideal process. That is, if the merger will be capitalized upon instead of just serving the stock owners.
To add a bit of perspective, from someone who sells classic video games for a living: this console's main point isn't to be affordable or play high-end games. Its target market probably already owns an OLED Switch, a Vita, PSP, every DS model and 2 or 3 Game Boys (one of which is modded with an IPS display).
It's designed to be interesting. That's it. Doesn't need to have a killer app or broad library.
Any utility it offers comes from the fact that it's something to add a bit of spice and fun to an already broad games collection, and possibly the clout that comes from showing other people that you own one.
From that perspective, I think these guys have absolutely hit it out of the park. Not surprised by the success of this at all.
I feel personally attacked.
BTW there is an abundance of VoIP services these days, from Facebook calls to Whatsapp to Google Hangouts to Viber to Fring.
