I think so too. It may be a bit unusual, but that isn't bad by any means.
Isn't the D2 still in production also? Supporting it might also get us a
boost with general touchscreen support (hoping it will attract developers).

I have no opinion here, I'm not into that target at all.

We still have some issues with the SD driver. The low memory have
buffering problems also. It might be too early to support them, but
having them in the testing builds forum was a good move IMO. Although, I
still think that's mostly the same (read as: I'd love to have them
supported if I wasn't a bit responsible for bug reports :D ).

It works fine, but the installation is flawed, so I don't think it
should be supported.

The Samsungs YH820 and YH925 could be supported right now. They're PP
based and have much code imported that worked for ages on other targets,
even USB. My only concern is the battery life. It seems very low, BUT I
haven't done a battery_bench, and I have no idea how much the OF does.
Part of the problem is that the backlight can't be turned of completely
(on the 925 at least), so that could explain the battery life. The
battery is also rather weak (750mAh only, for a HDD-based player IIRC).
The disk transfer speed is also rather low. They don't have plugins yet too.

But again, these not blockers IMO. We could support them, but we talk to
low_light before.

Most of them aren't even actively being worked on, actually. I agree.

Best regards.
