i wanted a carbon fibre rear cover for my iPad2 and was all set to purchase the ABS with inlayed CF cover from Mach3. having the ability to use the Apple smart cover was a must and even though i wasn't really crazy about the ABS plastic it was my only choice plus it is 2-3 times the thickness of the all CF cover. during a last minute search i came across Carbonfibergear.com and they offered a 100% CF rear cover that works with the smart cover. 2 days later it arrived and all i can say is it looks and works awesome. the smart cover works and all the cutouts are in the right places. i'm very happy with this cover and can't recommend them enough if you want all CF and the smart cover. on a side note, this cover is 100% CF and paper thin. if dropped it will not afford any protection whereas the ABS cover from Mach3 is definitely thicker and will provide some degree of protection.
