"I just got a new MacBook Pro - do I really need to buy a plastic protective case for the shell?"While I love these colorful SeeThru cases by Speck ($50), they aren't essential for protecting your new MacBook. However, they may offer some limited protection against spills, scrapes, and scratches, and they come in a variety of bright colors.
If you travel with your computer often, a shell may be a good idea for quickly sliding it in and out of your bag, but many laptop sleeves offer similar protection. Alternatively, you can carry your computer in a laptop bag that offers enough protection to keep it safe.
