My Logitech MX1000 has just died on me. This mouse is great but it appears that it isn't charging anymore. I suppose i will get the old multi-meter out and see if there is a decent voltage accross the charging pins, if so its a new mouse, bugger!
I think it is the power supply. I have scopped the recharging connectors and nothing, so I should be able to get a new mains adaptor for about £5, not too bad!
