The VPCSB [0] had a switch at the top that could manually switch between integrated graphics for better battery, or discrete graphics for better performance. It always felt cool turning it on before gaming.

Wow, that is pretty cool. I had never heard of a laptop with a switch for discrete graphics before. Sony definitely had some neat features in the VAIO line.
