I own a 930e, and it's a good TV. You'll probably be quite surprised at its backlighting given that it's quite good for an edge-lit set. (The 900e is FALD where the 930e is edge-lit.) Although, I will warn you that any off-angle viewing does result in a bit more of a halo effect in darker scenes. Similar to most TN panels, it does work far better when you sit in the "right spot". I agree with what others say about Android TV... it's pretty much garbage on the TV, and it does affect other more important things such as menu speed. Fortunately, you don't usually have many reasons to go into the menu, so it doesn't affect me
that much.
Also, do note that while Sony has mentioned Dolby Vision will be coming to the TV, it still isn't here yet. It has been delayed for months, and Sony has stated that they
should provide more information about its release in December. The rumor is that it will be released in March '18. (Sony's last statement was by the end of this year.) They did show off a working demo to Forbes, which the reviewer had good things to say about it.
Although, I do want to note that I wouldn't push for a more expensive set like this unless you plan on delving into HDR and such. That's really what this TV is geared for with its high brightness. You'll also want some good quality cables if you plan on doing High-Speed HDMI (18Gbps). If your cables don't support it, all you'll get is a nice, black screen. (I've had a lot of fun dealing with that problem.)
It probably better to use you built-in Smart TV function then a PC unless the app you want is not in their library.
If you use a good surround sound setup, you
do not want to use built-in apps due to the inability to transmit lossless or object-based audio to your receiver. HDMI's ARC only supports lossy audio (HDMI 2.1 will support Dolby Atmos), and that's the same as S/P-DIF.
