Quick Google of the main specs suggests max spec for the CF-53 is i5, 8GB 1333MHz, 500GB, 1366x768, 802.11n. 1.8-2.2" height, 5.8lbs without touch.

That seems a generation behind my rMBP; i7, 16GB 1600Mhz, 1TB, 3360x2100, 802.11ac. 0.95" height, 4.5lbs. Similar claimed battery life.

I haven't tried dropping mine from three feet or throwing water over it yet though...!
