I began shopping for a new computer on 3-2-16, and spent some time looking at online ads and reviews. I narrowed my choices down to either Lenovo or HP, based on precious positive experience with those brands and availability of several choices at or under $400.00. On visiting my local store, I was quickly attracted to this unit, due to its size, which is about half of that of the Asus tower that I had been using. On checking the technical specs, I quickly decided to buy it, given the processor speed of 3.7 gHz, much faster than I expected to find at this price. Having hooked it up and downloaded the software that I use, I am very pleased with its performance, which is very fast and smooth. I have one warning: be aware that the WIFi antenna included in the box with the power cord must be attached before one can hook up to the internet. This is not mentioned anywhere in the setup instructions.
