They are - dedicated silicon support for HEVC. That's how they can do it with such a small form factor and power budget. However a software codec on a modern PC should have no problem with HEVC due to the huge amount of available CPU.

It exists but it's slow which is why it's not standard in many video editing platforms yet. Encoding speed for 4k using the Divx encoder is <1fps. So a 2 hour film owuld take about 48 hours on an i7. I think there are some commercial codecs that are a bit faster like the Cinemartin one, but they're about $500. Makes sense if you have a small rendering farm, but limits demand at the bottom end of the market.

Of course you can just distribute the decoder, and of course the decoder is much faster (Divx is 28fps ont he same Core i7 IIRC). But the # of people with 4k displays right now is really tiny compared to the install base for HD, like I'd guess <<1%.

Well, Adobe hasn't added support to Flash yet. Plus, given their massive display pipeline performance problems, it's quite possible that they won't be able do 4k 10-bit HEVC when it's finally added.

They would also have to pay the added HEVC licensing cost for Flash Player, which is substantially more than H.264 was.
