This is a future proofing question. I don't yet have any technical problems, nor the means to cause any issues even. I bought this wireless keyboard and mouse combo the other day- http://www.newegg.com/Product/Product.aspx...N82E16823126197 I'm wishing to get another set for another room. The question i have is about interference. If i get another set, will both sets interfere with one another if both are in use at the same time? Their reach is quite far, far enough to reach opposite ends of the house anyways. Thanks for the help in advance. If there might be problems, i'd also appreciate any potential tips on how to eliminate interference.
