I changed from the previous model to this recent yoga 2 and regret it. Because the battery, the endurance on the former is superior, now hardly holds even when used correctly two days. In my experience (about 4 months of use) also makes the wireless connection again once problems. That the display and the speaker can be seen better, as comforting little, because for my purposes (no games and the like demanding use) handed the older Yoga 2 completely. Excellent but is the security tool, a software from Lenovo, which allows control of installed apps and allows, among other things, to escape these are not required for the operation sniffing rights.
