All, picked up the FE550G after owning an IBM T30 and subsequently an emachines m5414 (don't laugh...huge mistake). Anyway, I love this laptop. It is powerful, lightweight as far as widescreen notebooks go, and very comfortable to use. The screen is beautiful (as previously mentioned). As for the mouse problem:
My model has a touchpad icon in the taskbar. Double click and get a touchpad properties dialogue. Choose the tapping tab, then look for the "tap off when typing" option. This is off by default- enable it. This turns the tap function off while the user is typing which, for me, eliminated the relocating cursor problem. Not 100%, but MUCH better.
