Thanks for sharing the pictures. It does look great.  I totally agree that the patina looks sharp.  Really gives a high tech, slick device a touch of organic, human earthiness. 
Random question -- after you applied the leather conditioner did your cover get a bit of a "waxy" feel on the outside.  I posted about my cover getting a bit of a moist, tacky, waxy feel that stayed for the few days following and I was forced to let it dry off of my device.  I am wondering if it's because if used maybe WAY too much conditioner..? Or maybe too many coats? A few commenters thought it wasn't a big deal and just recommended letting it dry.  I also wonder if this is why my cover was maybe so, so, so dark.
Anyhow, after 4 days it's still didn't feel quite right I read about "removing" oil from leather using talcum power or cornstarch. I used talcum powder.  It lightened color to a warm, saddle brown (lighter than yours) and removed the waxiness and I am quite happy. 
Dd the treatment change the texture/feel of your leather..? I recall me original tan cover having a slightly suede-like feel... A most like fabric.  Now it is still soft (and very thin feeling) but definitely has a bit more of a smooth, leather feeling.
How about yours?
