Not all laptop keyboards suck. I have Asus laptop and the keyboard is great, much better than mechanical for me. Light on the fingers with proper mechanics behind tapping keys. And I am developer, so I type a lot...
I've used a lot of laptops and have still to find one which either types as nicely as a good mechanical keyboard or is as comfortable as the Microsoft Ergonomic (which sadly has rubbish typing action).
Of course this kind of thing is very personal, it depends on a lot of factors.
The 9550 keyboard just feels cheap and wobbly. The action is otherwise actually pretty pleasing. It wants to be the MBP keyboard but just isn't quite there.
