I bought a new MacBook Pro 13" computer recently and wanted to protect it from everyday bumps and scratches when not in use. It also was important to keep the whole package—computer and case or bag—lightweight and easy to transport. The Uppercase sleeve is ideal and, so far, I love it. I had no idea what "vegan leather" is. From the day it arrived until now, I had assumed it was real leather (it's not). However, it has the feel, looks, and flexibility of leather. The primary reasons I like this sleeve case are because it is light; it fits snuggly (your computer won't just 'fall' out—it takes an effort to pull it out); and, it fits easily into my briefcase. When I have a department meeting to attend, I carry it like a book to the location along with a pad for making extemporaneous notes. When it is my turn to record the minutes, I no longer have to unpack a heavy 15" beast with plastic top and bottom protection. The slim MacBook Pro comes out of the 'vegan' faux leather slipcase, and I am ready to go.The Uppercase 'Vegan' Leather sleeve for the newer MacBook Pro computers fits in a part of the system. It contributes to the synthesis of machine and work. I have been a Macintosh user since 1992, and I have had more laptop Mac's than I can remember. This case and computer combination is the best and most convenient one I have had. I give the Uppercase sleeve a full five (5) stars. *****
