i'm not saying 5mm is much but sometimes a few mm just feels quite different; like small to medium, or medium to big. but yeah in length doesn't matter too much either and 77 is still small... compare it to the vtc mini; it's almost a centimeter lower....... but the pico is even lower with "HEIGHT 70.5 mm" if that is even correct.
but anyway; blahblahblah ..seems nice and SMALL; i have ordered one, hope it ships soon~ish.
