As far as I am concerned the simpler you can make your life the better, and it is because of this that whenever I choose technology I usually try to choose something that does not need a lot of setup and which does not make the place look cluttered. One of the best things that I have found for doing this in the field of communications are Wireless Paging Systems, because the lack of cabling means that you really do not need to have a lot of clutter in the office or your other place of work. For me this is one of the most important points and the reason I love these types of system.
