Just purchased an A500 and have a question about the micro-SD card. When I connect the USB between tablet and PC, only the interal device storage shows. The micro-SD card does appear in Settings->Storage. The user guide suggests removing the micro-SD card and using a card reader to mount on the PC. Is it possible to mount the micro-SD card while still in the A500 as is the case with most Android phones? Any thoughts? I'm using Win 7 64-bit. I do have the USB update installed from Acer's website.
