Well, the newer Macs have limited USB ports so you have to either do a lot of switching around, or have a USB hub on your desk.  Now you have 3 or 4 cords laying around which look ugly and, worse, usually end up getting hung up on my mouse and causing me to rearrange stuff.  It&#x27;s not the end of the world, but I really, really enjoy my wireless keyboard&#x2F;trackpad and am looking forward to getting the new ones (at least the trackpad 2).
