Logitech’s got a new lap board doodad on the market called the Portable Lapdesk N315. It’s a $30 accessory with a non-slip grip and slide-out mouse pad.
There I go again, putting all the pertinent details in the first paragraph with total disregard for how I’m going to fill out the rest of the post. Oh, it fits laptops up to 15.6 inches. And it’s washable.
The $30 price tag seems a little bit on the pricey side but you may be able to find it for less at various retailers. If you have a sweet apartment with a spiral staircase like the dude in the above photo, though, you’re probably not to worried about spending $30 on something like this.
