I couldn't access the SD card using Root Explorer. Kept saying it wasn't mounted.
I could mount it in recovery and access it with my pc via usb but not natively on the tab with CM7 running. Not an issue with VG7. If I could have accessed the darn SD card things would have been better. I could not restore my Launcher Pro screens or Titanium Backup files. I know this is the wrong thread for these issues so could someone help with a link to a posting I would appreciate it.
I also like the position of the toolbar (not sure what it is actually called) in VG7 (lower left) than CM7 (upper right).
The internal storage is mapped as /SDCARD on VEGAn-Ginger but mapped properly (as per Google's method) as /EMMC on CM7. An actual real physical sd card would be mounted as /SDCARD if you put one in the slot. This is a pain for those without a real sd card to use and can easily be fixed by editing the volds.fstab swapping the /emmc and /sdcard mounts.
Doing that edit would give you back the ability to use the data stored on the internal storage as you were before....so you could restore you Titanium backups and your Launcher Pro backups. I use this method as I don't have an external sd card currently.
Also the "toolbar" is configured in the Settings/CyanogenMod Settings/Tablet Tweaks section so you can put those at bottom/top/left/right..which ever you want.
