Welcome to the forum!
Good value for the money, performance is great, battery life is on par with similarly spec'd ThinkPads and other brands.
While the build quality seems fine, the materials used do not seem to be the same quality as the higher end ThinkPads. The plastic seems less durable and more "plasticy". The silver trim seems like it will scratch easily. And, higher end features, like a swappable optical drive are absent. Of course, the Edge machines are about 1/2 the price of the higher end machines, when similarly equipped. A recent plus is the addition of the rubberized finish to the top cover and other areas, it's quite nice.
Bottom line, I have had several and I have not been disappointed. Be sure to read reviews for specific Edge lines before purchasing. Our family uses an Edge 15 with an AMD cpu for our media/music machine and it's been just perfect. My travel machine is an Edge E120 and I just passed on an X220 "upgrade" option, the E120 is that good.
