Tim Bray talks about a new IBM mouse that seems pretty sweet. Definitely bounce over there and take a look. Come back here, though. :)
I'm looking for a mouse for mary's machine, so I might get one of these and pass her my super cool Nyko air flo mouse, which I love by the way. The fan is surprisingly nice.
Update: In the comments, RoryB points to the iGesture pad by Fingerworks, which looks like a large pad that allows both mouse and finger movements to control things. Says these are the shit! After looking at their website, I'd have to agree that it could be really nice once you the hang of it. There are many gestures that use all your fingers, some that only use one. I'm definitely intrigued. Could it be time for a change of input paradigms? They also have keyboard/gesture pad combinations, although the price for those is larger.
The retail on the website is $159, but a quick search saw them at around $129. Could find any on eBay, though. Perhaps they are so great that people don't want to sell them?
Take a look at Fingerworks. If you have a little extra money and want to try out something that has the potential to change the way we interact with our computers, this might be for you. This is when I wish I had many more readers, so I could contact them and ask for a review copy. :) Maybe I could find a local 'zine, or something, to write a review for.
