Hi all. I have ordered my tablet, and am eagerly waiting for it to arrive.In the teardown thread, one commenter mentioned it looked like the 2GB memory was in an internal SD slot. Someone else mentioned they thought that slot had gone away in some of the photos.What kind of memory is actually used in this device? Is it hard-wired on the mobo, or can it be upgraded? Would one ever really need more than 2GB on a device of this type?Thanks in advance.
