I have the same experience you have: on non-apple notebooks I am not able to use the touchpads, even when they provide drivers enabling you to set pressures, hot spots, etc. etc.
I loved to use touchpads on Apple notebooks. I used to tap even when there was a button. Loved, because I had to buy a mouse when I received this magic buttonless trackpad. Nowadays, you do realize when you are in the same room with another Unibody user: clock clack clock clack clock clack clock clack clock
Really: I don't understand any more people in the Apple world. There are people claiming to return MBP or MB for a 2mm gap between the base and the screen (I have it, I consider it normal) or for a loose battery cover (I have it, I don't consider it normal, but it's not annoying) but everyone accept the C L O N K. In Italy we started using Unibody's touchpads in place of the bells in the churches. We go there, get synchronized and CLINCK CLONCK CLINCK CLONCK CLINCK CLONCK. We are very good and don't ask Apple for money.
I know in this world everything's subjective... but this is a tool where you usually spend 10 hours per day... If you like your C L OOOOONK, you should think about other people. We cannot be selfish.
