They might be able to cram a slightly nicer display
Samsung has DVI and two display ports. I am using a dvi to hdmi cable to connect to hdmi monitor on my one. Sound and video work fine. Lenovo would be cool, but series 3 should be fine, has 4 gigs of ram 6 usb 2.
the HDMI is not clearly recognized. To fix this issue I have to switch to TV than to HDMI manually and usually it stays open
Samsung TV has 2 usb. One at 0.5A and other at 1A. I had some issues like that on the lower USB.
Even the 399 USD is not what ou actually pay except when living in certain states like Oregon with zero tax. The average slaes no tax added
look for bargains on NextBuying and sites filtering offers with worldwide shipping is great for kids. Mine constantly want to watch Netflix in bed or do homework etc there and I'd find them with a laptop on a pillow or the carpet and overheating. It's not only the silent operation.
They might be able to cram a slightly nicer display in there or perhaps even 2 GB of RAM, but that would likely drive prices up. It seems really early in the product's lifespan for such a change as well considering the Lenovo models are still pretty much class leading on price, performance, and quality.
Think the phone does anything once you cast the movie or video. Everything is done with the Chromebook. I would suspect power from the USB. I know they say some tvs, like mine, have a service port that is the only USB and doesn't provide enough power. I use the ac adapter that came with the Chromecast. i've never had any issues at all with it.
