I go Intel (and so does Apple). Apple has a [multi button mouse](http://www.apple.com/mightymouse/). Hell has officially frozen over.
But if they have to do it, wow, it’s the way to go. I want to play with one in a store, but it looks fantastic for just $49. I have two 1920×1200 screens and limited desk/mouse space. That would sure help me get around, wouldn’t it?
This is my only concern, since I have no immediate plans to upgrade to Tiger:
>Of course, if you use a Mac but haven’t made the leap to Tiger, Mighty Mouse works with any version of Mac OS X, but requires Tiger to customize your settings.
further down the page it says:
>Mac OS X v10.3.9 or 10.4.1 and earlier: Assign primary and secondary buttons and activate Exposé. Display Dashboard in Mac OS X v10.4 or 10.4.1.
So if I’m understanding it correctly, if you have XP or 10.3.9 or earlier you have control over the buttons (I have to be able to switch the left and right buttons) but you can’t control the scrolling or use the buttons as a launcher/app switcher unless you have Tiger. Like I said, I’ll have to play with it to see if it’s still worth $49 with those limitations. It’s the 360 degree scroll that looks most enticing.
