I find 4:3 too square for both tablets and laptops as it seriously detracts from watching widescreen video content such as nearly all newer movies and TV shows, but 16:9 does have seem a bit too wide compared to height, especially on tablets when you try to use it in portrait mode and it seems ridiculously tall. I've found 16:10 to be a better than 16:9, and while I haven't had a 3:2 laptop, the 3:2 Nook HD+ from a few years back is probably my favorite table screen(shame about the rest of the tablet) in that it didn't compromise movies too much, but wasn't awkward in portrait.
