building a desk out of a slab of timber

Hi all



I'm thinking about building myself a new desk, I'm toying with the idea of using a single slab of wood to make the top.



I'm wondering if this is a good idea, instead of laminating one from boards.



Can slabs warp, twist bend more? Is there special techniques i'd have to keep in mind when working with the top.



any help would be most appreciated
