Yeah, that’s slightly more negative than my usual hook, but I just can’t help myself.  While I didn’t mind the Mighty Mouse so much, enjoying the click and the scroll-ball on top, this new attempt to re-vitalize the mouse misses the mark on concepts that ought to be a given considering we’ve used a mouse for a few decades now.  Namely, Apple completely overlooks ergonomics, usability, and customization.  The low-profile aesthetic may look nice, but it feels awful after using it for a while.  While the touch gestures seemed neat on paper, two-finger swiping left and right for forward and back in browsers is painful as you contort your hand into a freakish little gremlin claw to perform the action.  Finally, with a full-touch surface, so much more could’ve been done in the settings to allow user-defined actions in different apps.  It could be that a forthcoming patch rectifies some of this, but as it stands the shiny Apple design doesn’t do much to offset the steep price and questionable feature set.  If you absolutely need a nice wireless mouse and can get over not having the shiny Apple logo resting beneath your palm, check out the Logitech Performance Mouse MX.  It’s still pretty pricey, but more configurable and it doesn’t leave you feeling like you’ve contracted carapal tunnel after five minutes of use.
