I’ve just had to spend half an hour or so disassembling and reassembling my “Mighty Mouse”. (If you don’t know what a Might Mouse is, be thankful.)
Sure, the sideways scrolling is neat. But I think the convenience is outweighed by the time you have to spend trying to clean the damn thing to get the up-and-down scrolling working again. Eventually it stops working altogether, as mine did months ago.
Fixing it was pretty easy but it’s just not something one should have to do. I can’t believe Apple is still selling the same flawed design. (Steve, are you using one?)
All Apple needs to do to fix it is make cleaning the scrollball properly a two-minute job rather than a half-an-hour job involving screwdrivers, knifes and glue. In the meantime, if you haven’t bought one, don’t.
