This might shock you, but there are more precise numbers than "none" and "some". In fact, some of the ones that aren't "none" are even larger than others!
The only guard rail ive hit recently was when i was trying to get it to rename files ripped from dvd to episode names. I told it to try again and it did it. It wasn't even really a refusal it was just working on it and then stopped for content violation or what ever.
Ive never used Miracast. Does it not monopolize your WiFi card? Which would be fine if you want to show a keynote or something, but if you want to stream a video or anything requiring network access...
There's no technical reason it should. When I've used it on my phone, it's indicated that it's still connected to the WiFi network, but I've never specifically tested to verify that it was.
