Modern Offices

Does anyone else scour the internet for pictures of home office's for inspiration? I do it constantly. I dream of having a space like one of these where I can feel productive, organized and relaxed. I guess I'll have to wait until I have my own house to achieve this though. For now, I turn to pictures to keep my dream alive. What do you think of these rooms? Too cluttered? Or do you prefer a different style? 

Which one is your favourite?
