The Toshiba Satellite fits together with a thin Mousepad easily into the main compartment and is well protected from impact with the nubbed foam.
The side pocket is sufficient for the power supply unit, including cables, an external 2.5 "hard drive, a flat or little mouse (I use the Hama M3010 Wireless Laser) and small items such as USB sticks. Much more is not possible. In addition there is a stable, sufficiently adjustable strap.
After unpacking spread of the usual rubber smell, but that is quickly.
For me ideal to bring the Ultrabook with no frills, but with all the necessary accessories to work while traveling.
