One is $55, the other is $30. I had a Incase neoprene sleeve for my old iBook G3, and it worked quite well for me. So I'm wondering, is the Vyper worth the extra $25? I quite like the looks of the sleeve, but I'm not sure if it's worth the cash, or should I just get the Incase one? I plan to use it to protect my MacBook when I put it in the drawer when I have guests in my room (read: drinking buddies), or when I put it in my backpack. My MacBook stays on the desk most of the time.
