For some reason (technical? fashion?), just about every laptop today comes with a glossy screen, which makes them pretty much unusable when there's any light in the backgound.
I have a 13.3" 16:9 1366 x 768 pixels screen (horizontal 29.5cm x vertical 16.5cm).

I'd like some feedback from people who have tried those products or any not in this list.
