I noticed in some of the threads, it seems like folks are saying that they took the internal flash memory out, and the replaced it. In one or two cases, it seems like they replaced it with a bigger flash card. I know it's a little more involved that how it sounds, but is correct? Is the internal memory for where applications are stored a simple flash memory card? Can you really upgrade it by replacing with a bigger card? If you do, is there any real advantage? Does it only use it for applications and databases and will it be able to take advantage of the larger memory card? Is is there are certain point where you're wasting space cause it would never need that much for the internal card?
