netbook (10 to 11in 1280x800 LCD) no problem, laptop (1400x900 or above), requires some cash.
Laptop shipments are sequentially down year on year and vertical definitions such as x800 or x900 and just yuk. Even a 7" padphone now sports IPS 1920x1200 resolution costing retail USD200. Getting one of those 7" screens into a laptop would be neat as it would outdo most commercial offerings with a better screen. For $180 the 9.3" tablets with 2048*1536 screens available (e.g. Onda V975M). Getting one of those into 'Ubuntu laptop' would steal the show.
