About 10-bit and software problems - I should add that using 10-bit compatible decoder isn't enough, mxPlayer (many people think it's the best for watching anime and probably anything else) uses recent ffmpeg build, but it doesn't do any dithering on 10-bit->8bit conversion, so output may be even worse than on 8-bit video of similar size (http://a.pomf.se/bjvkgv.png ). So I find it funny when people are saying something like "10-bit plays fine on my Nexus 5 with mxPlayer, even with advanced subs".  VLC does dither, but when output method is set to OpenGL ES (which is on by default) it dithers down to 6-bit color, with Android Surface output method it works fine.
>(definitely no madVR)
GPU is much better on more recent Atom CPUs, so madVR won't give big performance impact on those, as it does most of job on GPU shaders.
>As for typesetting, are you referring mainly to karaoke effects? Because I haven't really seen complex typesetting elsewhere.
No, I don't. Karaoke effects are not so demanding, probably for two reasons:
1. Typeset for signs should mimic original sign and sometimes in can't be achieved without doing something hard to render (For example, there is no tag for gradient in ASS. To make a sign with 50 shades you do 50 of those signs, and cut them with /clip tag. Resulting image is combination of those clipped signs), but when you do KFX you just do whatever you find appropriate you don't have to render same text dozens of time (maybe 3-4 times for shadows and stuff) and you don't have to redraw it on each frame.
2. Signs are just a few seconds long, so you make it complex and caching will save you on playback. KFX could be 1.5 minutes long,  so caching won't help and you just have to make it easier to render.
I linked sample in my previous post (just remove bracket from link) - it's  25MB mkv file, part of commie's JoJo release. Typeset is basically zooming out wall of text with gradients. Here is original release with comments: http://commiesubs.com/jojos-bizarre-adventure-25/
>but if it's complex, should be hardsubbed. Great to hear that you're doing that
I don't. I just considering doing it. ATM I have script that automatically makes 720p MP4 reencodes with 8-bit hardsubbed video and I'm releasing a few shows under [RightShiftBy2] tag. It's far from perfect, though, because I'm doing on linux using wine to run VSfilter - it doesn't render .otf fonts well for some reason http://screenshotcomparison.com/comparison/73492 . I made a roundabout solution by converting those fonts to .ttf, but there are some other issues, maybe some of them are just text encoding issues, not font. Still, I won't start doing this semi-hardsub thing unless I deal with those issues. Maybe in next season.

>3. I'm surprised I haven't heard more about tablet users in the last couple of years.
It's not like whining on internet will help you with this anyway. Especially since tablets and phones is not considered "real" computers unlike x86 computers.
Also, 480p versions was common since forever and [DeadFish] started doing reencodes before 720p-compatible tablets became that commonplace, so most of tablet users already had an acceptable alternative right after buying tablet.
