Hans....this Lenovo laptop that I have is still quite new, and I have only been using since the middle of March. But it seems very well built to me. I have managed to get it to last 6 hours in between charging !
I am not really a fan of touchscreens, as I find them slow and sometimes very unresponsive. However, the Lenovo comes with a stylus that slips into the side of the keyboard, and would appear to be "powered" as it has two battery contacts on it that must re-charge it when in situ.....not seen that before !
