Mouse Devices Questions & Answers
What a weird mouse...

Weird- yes, but I think this mouse would be very comfortable.. Has anyone used such a thing? Instead of moving the whole mouse...just scrolling with the trackball O_o...
Display mode:
It doesn't look that bad at all, it's just odd. This thing never seemed to get much popularity, but are quite useful for home theater PC or in-car pc without touch screen. However it would definitely take some time to get used to moving with your thumb instead of your whole hand. I wonder how many will actually spend their cash on this.
Now that is some uncomfortable mouse. It may be OK for your hand but after a while i can see how my thumb gets owned. It is no good for gaming, no good for browsing, it could be comfortable in office and home theater applications though. I still prefer the logitech MX Air over this one, at least it gives you option to use it as a regular mouse as well.
Cool mouse, It isn't that uncomfortable to use those as you think, just different. Of course you won't be fraging in CS with this thing but, its pretty adequate for any other usage, beyond gaming.
