One of the videos they link to (http://www.youtube.com/watch?feature=player_embedded&v=xl5qn...) highlights a lot of different concerns. Among the obvious were the shortcut keys (e.g., Ctrl-Z) and the reviewers losing the ability to switch their screen to full screen. I'm not seeing these problems address on the frogpad page.
Note, the stickers refer to the previous $60 or so product which provided some overlays on the magic trackpad.
They apparently launched the new product site (not the product itself) on Jan 1, 2014.
