My sweet spot for laptops is 4:3 @ 14in, but 16:10 @ 15.6in is a reasonable choice as well.<p>16:9 on the other hand has no place in anything but very large desktop monitors (say 27in and above). Whenever I have to use someone&#x27;s 13in notebook - inevitably 16:9, even expensive ones - it makes me want to scream. It&#x27;s like peering through a mailbox slot.
