Am completely satisfied with the Convertible. Both with and without keypad, it is easy to operate. The quality of the display is good, even with a protective film can be the touch screen operate flawlessly. The battery lasts usually 8-10 hours, depending on usage. The Internet I could connect through Wi-Fi and 3G stick. Small flaws has to operate the touchpad on the keyboard. Every now and then gives the touchpad Y when touched. The built-in SSD is 32GB for Win 8.1 bit short, but still enough if I install any memory face.
