Why hasn't M$ thought about using mobile technology? Stop and think a min. The size of a P.C. vs the size of a laptop. And dont even start with the whole limitations of a laptop! M$ doesnt build xboxes to have them stripped down and rebuilt. They look to avoid that at all cost. They can incorporate the laptop HDD and DVD technology into an xbox to achive thier goal of size. Why the push for big fat and bulky raw power. You want this, build a P.C. If you want a game machine, think out side the box.
People love lan parties. How many times have you packed up your xbox to play halo at a friends house? How many times have you packed up your P.C. to play Black Thorn or Mechwarrior at a friends house? Retrospectively, when was the last time you packed up your laptop to take your files to work, school or vaccation? When was the last time you took your P.C.?
