Hey, I'm looking for a mouse to go with my LED ACD to use when the MacBook is shut. I think I've narrowed it down to these two: the Microsoft Natural Wireless Mouse 6000 or the Logitech MX Revolution I need a wireless mouse which has multiple buttons which I can customise (I'm happy to use Steermouse to do that if I can't do it through OS X). Those aremy main concerns, so if you think the mice I've chosen above are expensive for that and can suggest a cheaper alternative, then please feel free. For me, the most important feature the mouse needs to replicate is the trackpads multi touch gestures. I constantly use the app switcher, exposé and show desktop all the time using four finger multi-touch gestures, so I need a mouse with enough buttons or functionality to be able to do this. All comments and advice are welcome. Thanks.
