It's shaped the way it is to fit people's hands. The Wiimote has hard edges which make it uncomfortable for long periods of play, thus the cylindrical shape. It's tapered so that people of many different hand sizes can hold on to it comfortably. The squishy ball (not hard like a ping pong ball) on the top houses the LED that lets you get 1) precise location info and 2) works in the dark. It's all very practical, and the developers have explained it many times before.
On the topic of its shape being cylindrical in comparison to the Wiimote, it better matches...

Hm, I wonder why they would have chosen to do that. It's not like there are games coming out for each of those.... are there? :P
It does look like a microphone. People who think it looks like a... sex toy... probably haven't looked at very many sex toys. Sure it could look like it in a VERY round about way. Then again a microphone could look like a sex toy in a very round about way. A doughnut could also look like a sex toy in a very round about way. Can you tell the difference? Hopefully you're not intellectually retarded.
No one's saying its a dildo, they're just saying it resembles one. To whomever said the a microphone could be used in the same manor, well duh... I'm sure they have been too, I'm also sure that the move remote is a lot more pleasurable then a mic as it vibrates making it more closely resemble a sex toy. So its not necessarily a dirty mind, It's people who can think about more of the options then some. Shape and function makes you think of a sex toy before a mic. Just shape alone will remind you of a mic. But either way... GREAT CONVO! I'm still laughing about it.
