My father in law (early 60's) want an new mouse for Christmas. He doesn't game, always sits at a desk in his study (making wireless of limited value) and mainly browses the internet or uses office packages. Based on that, I'm looking for a wired mouse with a limited number of buttons. No budget constraints if there is a value, but anyone got any suggestions? I'm thinking a Logitech M500 for about £25 (as I like my G600 gaming mouse from them) but open to any suggestions.
