Since when does apple consider looks before common sense, functionality, and ergonomics? The ipod started the trend of minimalism and touch sensitive interfaces, 2 'features' I think are counterintuitive.
Let me explain:
1. The mac is known for ease of use, but a person who does not know about the mighty mouse will not know by seeing it, that it has 2 top buttons.
2. When using a traditional mouse, ones fingers rest on the buttons. With regular mice, this is fine, since there are actual buttons to be pressed. With touch sensitive buttons, they will be likely to be accidentally pressed.
3. clicking and dragging is difficult on current apple mice due to the button being the top of the whole mouse. this trend seems likely to continue.
4. the trend of apple creating its own design methodology based on aesthetics and tradition (both mac based and NeXt based) is not good for the user. All because the mac always used 1 button before does not mean it needs to hold on to that tradition via 'single button charm'. Apple is trying to hide the fact that it is becoming more like a pc. First there was no context menus, then ctrl click appeared in os 9 and os x, then apple tab task switching like on windows that allowed mouse input, then multi button compatibility in os x out of the box, now a pseudo 2 button mouse that looks like a 1 button mouse. Just admit it apple! Give users 2 buttons that are unambiguous.
5. This may very well be a great peripheral. I will try it out and if I like it, will by it. I'm just sick of the reasoning behind the design, and see apple's ergonomic choices putting users 2nd, which should never be the case.
