Yes, I remember reading that. But my car I think is only Class 4 or 6. I haven't tested the speed, yet.

Maybe I can partition the SD card, and then put /usr and /home, or anything else that can be loaded in to RAM, on the eMMC, and partition the SD card for swap, etc, root, var and temp. This is why I would like to use another OS besides Maemo, because Maemo can't easily be this flexable.

You may have heard one person's opinion. I think it can either save battery (by disabling watchdog) or shorten battery life (by enabling terminals) depending on how you use it. If you or anyone know(s) any details of (the) side effects of R&D, and how to treat them, please let me know in detail.

No, that's not necessarily going to be true. I think FSO, SHR and Nitdroid, as an example, all have GPRS/GSM/HSDPA+ and whatever all working. Some of these may have problems with the camera and GPS, but FSO (and maybe SHR) says that it doesn't. I can always use ofono, and that runs in the terminal, but I don't know if I can make phone calls with a GUI. Maybe I can firgure out how to make one in Ruby or Python if nothing exists for that.

Unfortunately, I think all of these OSes have problems with voice. Even though they can make the calls, there's no voice output on the recieving end, which sucks. But hey, maybe someone, even myself, can write the firmware needed to fix that problem.
