Whiteboard sticker for your laptop
We used to make whiteboards at a printing company I worked for. It was mainly just white SAV (self adhesive vinyl) with a laminate over the top.<p>Ten dollars is an awful lot to pay for that, when you're talking about just a laptop size. You'd be looking at much less than a dollar in materials.<p>Edit: Though the fella obviously recognises this, and has a DIY on the page... And I can see people buying them for the convenience element. Still though...
