Yeah, the benefits of 10-bit are vastly reduced in most non-anime video, so, combined with the poor support, it is generally not used much anywhere else. Since so few people actually use it, it'll be a long, long time until we start seeing hardware support for it - frankly, it's likely that h.265 will have become the anime standard before we start getting hardware support for 10-bit, if we get it at all.
That said, 10-bit is pretty much the current standard for anime releases (at least in HD), so if you want to watch most of them, you do need to be able to play it, or convert it to a different format. Which means using a computer (or phone/tablet/etc) with the power to handle it.
