I have one and have been using it as a Lenovo replacement at work for about 3 weeks. I'm very happy with the batter life and the weight. The keyboard is comfortable and not too loud, and the Horizon VM app lets me do everything I need to do.
It's also kind of a head-turner. My entire company has Lenovo Thinkpads, so when I'm in a meeting it gets noticed and I get a ton of questions about it.
