I'm thinking about buying the Samsung Galaxy Tab 10.1. It will have a modified version of Android Honeycomb (TouchWiz). Is it possible to install original Android from Google on it?
As soon as someone unlock the bootloader(I don't know if they already done) someone will come up with a stock default theme ROM. You can stay tuned at XDA-Developers for news about this.
It's absolutely possible, as long as you can access the bootloader (ie. unlocked bootloader).
