In my last post I mentioned how it would be good to have ZERO internal storage so that everything would be programmed to be stable with the sd card. I would like to expand on that.

ROM booting from SD card. Want to use 2.08 ROM for one thing and DCD 2.3.2 for another? Get two sd cards and plug and play. All caches and programs would work from SD card because they would be tested to work from nothing else. Installing a new ROM would have zero risk. Sprint repair centers could fix customers problems easily by seeing if problem reoccurs with a stock SD card.

Any internal storage used to speed booting could act as a cache. So it could detect if the SD card was the same, good from the stored cache if so, and boot from the new card if not.

Also, this would make having two microsd slots more attractive since the cards would have more uses.
