I like the magic mouse for everything except actually using it. I've used them before and they just don't work naturally with my hand; they're way too flat. Plus I definitely prefer to have all mechanical with my mice and keyboards.
To me, it's more comfortable than any other mouse on this planet. But that's your opinion I guess.
I hope you're not trying to place your entire hand on them though- if you are, then yes I would agree that that position is uncomfortable. I have my pointer finger on left click, middle on right, thumb around one side and index(one between pinkie and middle) on the other. To me, that is comfortable.
But it is, again, your choice. You might want to consider the Mighty Mouse, which I used to use. It's more like a regular mouse, but still has that touch thing and one-button(uses touch right-click, it feels natural) and has buttons on the sides you can squeeze. It also has a 360 scrolling wheel, but it is a physical wheel and not a touch wheel. It is $10 cheaper than the magic mouse at $60. You do have a middle click, just push in the scroll wheel and click. That means it is a 4-button mouse, but you can disable the functionality of the squeeze buttons.
OH, and the ones on Apple.com aren't wireless, but you can probably find wireless ones still in their package on eBay. I don't think apple makes the wireless ones, but I have seen them before. They are a bit heavy, though.
