I'm looking for a substitute of my Logitech MX1000 laser with a corded mice alternative. The ideal mouse would be one that fit a large hand, so quite 'thicker' than most of the mouses around. The MX 1000 is enough good for me (a larger one would be better) but I don't like the cordless solution: sometimes I forget to recharge the mouse so I cannot use it, usually during the most critical situations...the Murphy's law hits! I never had on my hand a G5 laser or a MX 518 for a direct comparison. - Anyone uses one of them or have a suggestion?
