No. We only have two power alternatives:

1) We don't have enough power to use the disk.
In this case, going into the charging screen or regular Rockbox has little difference - you can't do much except charge the batteries.

2) We *have* enough power to use the disk.
This is by *far* the most common scenario. In this case I believe it is much better to actually boot Rockbox and resume playback or whatever else the firmware is programmed to do, than to just enter a charging screen that requires manual interaction to exit. Think car mode or someone using a simple power timer to wake up his archos.

This sounds like a good idea.

If I have to choose, I think it's better to be clumsy in the rare failure case than being clumsy in the much more common success case.
