I have a quick question here. I looked into the spec of the sprint and verizon galaxy tab. Looks like they are almost identical except that the sprint has 128MB One D-RAM installed and verizon version does not have. I also read from a blog which said that the verizon version was more feature crippled, such as it has no option for bluetooth keyboard or some HID (human input device). Anyone knows if the 128MB One D-RAM is not in the Verizon version? Is the claim of peripheral add-on feature limitation on verizon version true? What's the purpose of this D-RAM memory? Does that mean sprint tab is supposed to have better performance?
