I got PS2 slim for christmas and i do not notice any laser problems withit. It is about 4 times smaller then normal PS2. When i playeed regular PS2 i was astounded at how large it was. PS2 slim is much smaller then X-box becasue if memory serves PS2 normal is smalller then X-box. Anyways I believe the overall system is the same except it has a built in router and such.
