I believe the older F/FX series uses the aps pad.. GRX/GRS/GRV and newer? (not sure) use synaptics.. Theres not much difference these days in the actual pad more in the software..
Does anyone know how the Sony Electro Static touchpad compares with Synaptics? I love Synaptics--it has many features that I use all the time. I sent back a computer that had a crappy ALPs touch pad. I'm hoping Sony's is alot better than that.
Thanks!
