had mine for 2 weeks now.
things I like: Does not get warm, makes no noise, and small (thus more portable) adapter. Also, many reviews mentioned the nice keyboard, something I didn't care about at first. However, it really is a nice keyboard and has made typing more fun and efficient.
Things I don't like: The adapter cable is too short for my liking (a bit over 2meters I'm estimating). The glossy screen! My previous notebook had a matte finish, so never had any issues with reflections and lighting etc. I knew the glossy screen would be reflective but I didn't expect it to bother me this much. And lastly, wifi connectivity problems when coming out of sleep-mode. If you google it you will see this is a common issue with Lenovo. I changed some settings to work around this issue, and for now it seems to work. But I'm still not happy that my new notebook has problems with a basic function such as connecting to the internet.
