Adding weight to devices to make them feel better is stupid. Thinner and Lighter is the new mantra. Just redesign the case to make it super ultra-small and people will gobble it up.
This is not a new phenomenon. Atari made the same blunder with the Lynx, adding huge wings to the side of the device to make it bigger and more important looking, but making it impossible to fit in a pocket because they didn't want it to be confused with those little Tiger electronic toys. A super-small and portable Lynx might have actually found a market niche (although the 800lb Gorilla of the Game Boy would have probably crushed it anyway).
