Hello all, In a bid to reduce RSI I decided to get a Kensington Expert TrackBall after reading many many different recommendations on the product. I don't know if it's just my setup or my hands distaste for this product but I hate the damn thing. It's just too slow and imprecise for my needs (mostly Photoshop, Transmit, Mail, iTunes, lots of browsing), I need something that is quicker to use, much like a normal mouse. However, I'd really like to try and reduce any RSI like symptoms I may be getting, so I'm open to any suggestions you may have. I spent £70 on this stupid mouse and Apple want to charge me £30 just to return it so I'd like to be sure before I buy anything else. I can't try anything as nowhere has anywhere near a decent selection, so I have to rely on reviews. Also, most of the more expensive mice seem to be cordless/wireless/bluetooth. I've used Apple's Bluetooth mouse and it is too sluggish for me, especially when it needs a shake to wake it up. So preferably corded versions. (Unless there are any wireless mice that don't act like this). Any recommendations greatly appreciated!
