Mighty Mouse--Better Ergonomics in a Buttonless Mouse?

I'm not a Mac user, so I'd never taken the time to peruse their mouse selection before, but after chancing across the "Mighty Mouse," I decided I liked the idea.  It seems... ergonomic.  First off, you use the whole mouse to scroll, rather than a tiny scroll wheel embedded in the top.  (From what I've read, any time you're using larger muscles, you're less likely to put strain on the small muscles in your hands and fingers.)  Second, it has no buttons.  Instead, the top shell is "touch sensitive" so rather than pressing down or clicking, you just lightly touch the area where the buttons would be on a normal mouse.  It also has interesting-looking "squeeze" and "roll" features that allow you to do things you can't on your regular mouse (short cuts for surfing and navigating applications, it looks like).

I read a couple of comments from people complaining about the $49 price on the Mighty Mouse.  It does seem high for a mouse, but I suppose the touch technology would add a bit to production costs (I know my iGesture touchpad was about $150, and the FingerWorks TouchStream board cost me $300).

Apple wasn't the first to use touch sense technology in a mouse. That was Hoverstop, a mouse that senses if your hand is on the mouse and then monitors if you actively use it. If you are just holding it, it vibrates to remind you to take your hand away and relax. You can read more on their website, www.hoverstop.com.
