Hi Burr, thanks for the info.

Yes, tried various mice and stuff - the tablet turned out to be the best.

However, strange to tell, I tried out a trackball just before Xmas. Unfortunately I have also developed shoulder problems (at work, I'm fine at home) and thought the trackball would help. I tried the Logitech trackball pro and it didn't help that much, plus it did make the wrist somewhat sore, though not as bad as the mouse. The HCI specialist and Occ Health nurse reckon it's because the keyboard is too wide and pushes my arm out too far. So I'll be looking to get a narrow keyboard without numeric keypad. I don't have this issue at home because I don't do as much typing and have the tablet much more in front of me (day job is technical author/illustrator).

I see that the Kensington Mouse Expert Pro is a very different beast from the Logitech, so I'll mention this to the experts at work anyway. I'm okay with the tablet at home and all my personal apps are 'tablet friendly'.

Anyway, thanks again.
