No... actually I want an honest response on how redundant this item is. There's no need for it, it's just money out the window, it's not going to make the trackpad more functional.
So there's two sides to this:
1. Apple failed during the design of the trackpad
or
2. People are actually that stupid that they can see a point in this.
You've got to be putting us on.
You really think that this has no purpose?
How about for a home theater PC, where the single trackpad/keyboard unit is EXTREMELY handy while sitting on the couch?
Or, similarly, anyone that wants to use a computer without a desk directly in front of them. Sitting back in a chair, for example.
It's a brilliant design, and something I'll be buying as soon as it's available in UK shops.
For the other poster asking about people using the trackpad - I have one for each of my machines. So much easier than a mouse. Don't need to worry about what surface I'm mousing on, don't need to worry about desk space (or a desk at all). And the multi-touch gestures are brilliant.
