The etched Mac lids look extremely cool! The stick on wiggles for grip look like a good idea for those of us who seem to find the current alubooks remarkably slippery - I know that I've almost dropped my AluBooks many times and I'll be getting something like these now. (I guess you could use those strips you fix to the bath if you were being cheap :-) )
As regards the handle, I had one of these with my Titanium 15" PowerBook and you need to be very careful about the strain that the handle mounts put on the screen hinge assemblies. I had one eventually break and had to replace it. Your mileage may vary of course .... it does make it a lot easier to pull out of a sleeve without struggling for grip.
