We’ve just had a play with Motorola/Symbols MC55. Its billed as a enterprise digital assistant (EDA). It looks good bridging the gap between the MC75 (VGA screen, camera, laser barcode scanner, ruggedized) and MC35 (QVGA, light, non ruggedized).

I guess compared to the MC75, their are a few compromises. The build quality looks great. However the camera/barcode integrated scanner looks a little light weight compared to the more expensive MC75. However the keyboard is way better than the MC35.
