I think the case for a Magic Trackpad 2 upgrade is stronger than it is the Magic Keyboard. The bigger size and easier click at the top are compelling and while Force Touch isn’t all that just yet, I suspect it eventually will be.

Funny that the selling points for both devices is in part their size. Except it is the keyboard getting smaller and the trackpad getting larger. Goes to show just how important touch controls are becoming, even on a Mac.
