The original EASD version came with an extra 2GB of RAM (1GB in this case) and a micro SD slot. That is, you have the ability to put that same amount of memory on the EASD model. If you still have a problem using the EASD model please do have a look at your device reviews. Please note: You do not need to have an ESD card as long as your battery or CPU is at full charge, but you could be driving a lot of other devices all the time. If you need anything, please see the main site.
