After hearing one of the touchpads of a Sharp laptop, I would say stay away from those...because those buttons will click louder than your desktop mouse. FPS would definitely be easier to play with an external mouse, but that's if your laptop can display enough FPS (Geforce2 Go or ATI Mobility should do that good enough). Some people will get used the trackpoint really quick, while others will have a hard time learning it...I guess you'll just have to see for yourself. If that doesn't work, you can always get that external mouse.
