so is linux a good substitute for XP or are you very limited? for example editing movies, photoshoping, downloading files from torrents, playing new games, voice and video chatting over skype/ICQ/msn/ventrilo etc.. ? and other various stuff ppl do? Is it like a mac, you can do everything but you'll feel like a retard the first couple of weeks? :P what's the downsides?
