Actually - the memory implementation of the Verizon Ellipsis-7 pad precludes installing any apps on the add-on memory card, but in some apps - it is possible to direct their data files to the memory card. The internal memory on the pad is broken into a /system partition and an emulated memory card /drive0. The add in memory card appears as /drive1. Originally the firmware restricted the size of the /system partition to 1GB, which caused problems with people who wanted to add lots of apps. Verizon released an update that fixed this, and apparently allows the /system partition to resize itself or grow dynamically. Problem is - there is only 8GB total memory shared between /system and /drive0 - so it is probably possible to run out of memory if someone was to store lots of photos/music on the emulated /drive0.
Just a thought - dunno how hard it would be to do since I haven't done any Android programming - but some apps do allow for data storage location selection by the user, and if one were making a big log for diagnostics purposes this might be useful.
Thanks for the response. If you want any help in beta-testing any of this - Stephen has my email..
