Furniature arranging in living room

I think that the most difficult thing to figure out is a logical arrangement of furniture. I have been trying for several days now to sort out the best organization for the living room so that it has room to move around and I can relax or be up and playing the workout video games for the Wii, but every arrangement I think up has flaws that do not work. The most significant flaw so far is the inability to work on the computers and still see the television, so I can't watch something and get my work done at the same time. I am starting to think I need to get a smaller TV and set it up with my monitors so I can watch the news or other programs while still working.
