Etsy seller michellechristina is back (we debuted her colorful creations last year) with more designs to choose from and in many more hot colors. My latest fave? Her collection of bubble decals which will spruce up the exterior of your laptop for only $13. If the pink is a bit too much for you, I also like the subtle white, black, and silver designs. And if you really want to go color crazy, there's a rainbow of colors to choose from.
