The Z-Book is a cute little machine with enough grunt for even power users. I quite liked the fact that the Operating System (Linux) was pre-configured and I did not have any issues with Device drivers, or getting the camera or sound to work. The Laptop (or Netbook) worked out of the box and flawlessly at that.
The little machine tends to heat up a bit though after 2-3 hours of use. But I guess that is to be expected given the small dimension. Even with 5-6 apps open simultaneously (Open Office, Browser, Email), the machine was no sluggish and I was quit e pleasantly surprised with the performance.
Battery life is decent at about 2 hours and you can buy additional battery if you expect to work on long flights. The Z-Book also comes built-in with Bluetooth, WiFi, Built-in camera, Modem, Ethernet. nGood to see an Indian company producing such good stuff.
