we have sold a couple of N80 bundled with the production machine, very reliable and excellent acceptance from the customers. The screens of the Sonys are one of the best types you will find.
Look also at the features, even the standard screen type (15.1") is good value for money.
But always think about the use, if you want to do graphics etc, forget the LCD screen as you never ever get matching colors.
For almost all other purposes, I assume it is a question about available change...
