Internet "addictions" are only a problem if they interfere with your life in some manner. I spend a fair amount of time skimming through RSS feeds but my PC is on a built in desk in the kitchen where I can turn my head and interact with anyone who is present. Really no different that reading a book in the living room. The same would apply to using a laptop in the family room. Some people bury their PCs in an office which may isolate them. This could predictably alienate your spouse which may rise to the level of disrupting your life.
