I am owner of a Sony VPC Z11 (13.1 ") with a leather protection, this latter slides smoothly in this case. I find the large pocket a little just to put food (VPC that of the Z11 is not fine), headphones and mouse without son but it goes without hump and more easily if I detach the cord from the power supply. Small pockets on each side of the handle (or handles) allow me to drag my phone charger at one end an external 2.5 "drive of each other. The small pocket on top of the large pocket with access to the side is a little accessory but I slipped a small pouch carefree. inside a pocket lets slip a thin notepad or a few sheets of A4. There are also three small pockets that protect the CD / DVD, a mobile phone and to put such pens.
Acquired at the price of 31.75 euros (sold and shipped by Amazon), whereas if I remember correctly, it was on sale at the time by Sony around 70-90 euros.
