“one could comfortably do everything they're used to with a typical mouse”

Like lifting the left finger up to be able to right click?

And haven't I seen someone else invent one of these before?

Not convinced by this idea tbh. First off it looks quite tiring for the fingers if you think about doing this all day. Plus all those things can be done easily and quickly with a normal mouse that has a few extra buttons and a scroll wheel such as my MX518.

What a blatant copy of magic mouse…

I don't see anything here that would make me want to swap out my current mouse, nor do I think, atm, that I would consider this when it comes to replacing my mouse.

“One can use two fingered gestures to manage Windows”

I've been doing this for years with no effect, am so glad it'll work now.

Sounds good for using managing windows faster but. I wouldn't want to switch between this and a gaming mouse all the time.

I tried a magic mouse for a while but couldn't get on with it as it was so flat, this looks a lot better as it has a bit of shape to it

Whilst the promo video admittedly put a great big whole in the middle of my initial cynicism, there is no way I'd choose this mouse or any other I've seen over my 2001-model Logitech Cordless Optical Trackman.

It really is the mouse of mouses/mice - except it's, uh, not a mouse but a trackball.
