best of both worlds here

MS Trackball Optical (black one) in PS2 port for surfing is elite

MS Intellimouse Optical in USB for FPS'ing.
No more wrist mullarky when surfing, still Rail gun ace when FPS'ing.
Why do so many people seem unable to come to terms with the idea that using both is the best compromise?
People try a Trackball, try FPS/gaming, hate it and bin it without realising the trackball's strength is surfing etc not gaming.
