and of course go all devices, as indicated, to 12.1 inches in there. But probably all under 12 inches is only conditionally suitable. Why -> unfortunately schlappert my 11.6 inch - netbook in this envelope back and forth, because the sleeve for this device is a good 4 cm big. But for 12.1 inch devices securely fit. Otherwise, a standard product which served its purpose and the netbook or subnotebook protects against scratches and light bumps! As an additional protection in a stable 13 inch laptop bag but too big.
