This is good for the backers to invest so much in the 2nd product version.
For me this sits in an ecosystem of options. I already have a Smartwatch, smartphone, tablet, Chromebook, Chromecast. The Nebula II's amount of pixels I can get in a 3 year old $99 phone with more brightness. The Nebula's size I can already get with a HDMI cable off my phone or tablet to a display or even smaller with a Chromecast. I have plenty of Soundcore speakers, very small from Nano upwards. Flatscreen TVs "55 came up recently for $199.
If this were a $99-$199 product I'd be in why not mode but ..... do we need to pay $349 for a 720p projector?
I'm sure version 3 will be where this get interesting, more brightness and resolution, and version 4 where manufacturing costs drop and so a $199 price appears.
