This brings up another interesting scenario... So if 2.1 comes out and is NOT rootable what will new/refurbished Droid be 'flashed' with from the factory... it would REALLY suck if someone had to exchange/replace their phone and the replacement had an unrootable ROM...
Be about the same as if root can't be reversed... you would NOT be able to exchange the phone for warranty or insurance... you'd essentially have to drop it in the toilet and hope they don't (or can't) pull the ROM info once they get it at the reconditioning facility.
