So i've come to a painful realisation that i simply cant use my V270 as a heavy duty day-today mouse with my iMac but rather it has to remain a notebook mouse as i originally intended. I tried to use the MM that came with the iMac but it's ergonomic-al design is very poor and my hands end up hurting even worse than the V270 As a result i've decided to buy a new mouse i've been looking at the MX Revolution, i got to play with my friends one briefly and it was very comfortable and just felt right in my hands but its too freaking expensive £51!!!. However, if i have to, i'll spring for it eventually because at the end of the day you can't put a price on easing pain and preventing RSI. Another mouse i was looking at is the slightly older MX 1000 and thats cheaper at £36 and i'd easily take that but i dunno how well it works. Was wondering if anyone has experiences with both or individually and how they like them. Which would you suggest i go for? BTW if anyone has any recommendations for a wireless (RF) desktop mouse for a decent price...i'm all ears Thanks in advance.
