This has been a lifesaver for me! My back has been killing me lately, especially since I sit in front of my computer for more than 10 hours on most days. The one thing that I really love about Zen is that the posture nudges are so well executed. They don't come too often so that they don't annoy me while I work, but they come often enough to remind me that I'm slouching! This is truly amazing...
