This posting is of considerable relevance and strongly has my attention:
Does anyone have feedback as to this mouse being more practical than the wireless MX 700. Does anyone find the MX700 to have problems with interference in a room full of computers and printers and phones and stuff ?
We presently use a corded mouse (5 buttons are a must) which is ergonomically fine. The cord is no problem. Maybe the wireless will be that much more comfortable. However, I get concerned or curious about potential interference from other electrical interference.
On the other hand if there is no way interference would be a problem, due to the MX 700 being on some kind of dedicated and way off the spectrum band, then we would very possibly bypass the MX 500 and go with the MX 700.
It would seem that even the slightest interference might be "sticky" (pun) with the actions and functions of mice.
I also suppose that one could get a mouse chord extention chord, for the MX 500 if one so wished.
PS
I do have several 2.4 Ghz phones and I would imagine that there could be interference. As it is my 2.4 Ghz phones are interferred with when I am in the computer room. This might portend that the MX700 would like be interferred with.
