The good news is that you can change thisbu following this procedure:
1. Get the AndoidID from your device or from an emulator (requires to install and use the Android SDK). A procedure is described here:
http://www.slatedroid.com/wiki/index.php?title=Fix_Market_For_Slates#Make_a_new_androidID_with_the_Emulator
and/or here
2. Install the Firmware
(See http://www.slatedroid.com/eken-m003-firmware-development/)
3. Put the AndroidID from step 1 back to your droid. (This is necessary otherwise all devices using the firmware have the same AndroidID, making it impossible to use the Android Market).
(Same link as point number 1)
