A laptop case of any kind is desirable to prevent damage to your laptop. The hard case acts as a second skin for your laptop and I prefer it over a laptop sleeve for its 24/7 protection. Most packages on amazon also come with a keyboard protector which is a great feature that keeps your keyboard clean and safe from spills. These two pieces together are around $10, which is very inexpensive (compared to the cost of a new computer) and feasible. The range of colors and patterns also allows you to add in your own unique style.
