I have been running CM10 off the external SD Card and it has been working great. However I need to connect my charging cable to get CM10 to boot off the external SD Card.
I will take the plunge and install it internally. Hopefully to boot CM10 off the Internal EMMC, I will not need to plug in my charging cable any more.
@livramax or anyone else who is running CM10 off the internal EMMC, can you please confirm the above statement.
