A full review of the Acer Aspire One 722-0473. The Acer Aspire One 722-0473 is an 11.6-inch HD LED notebook powered by an AMD processor. What we have here is a small simple device that is feature packed and relatively easy to use. Lets the the negative out the way, if you are getting this notebook, be aware it comes with only 2GB of ram and I suggest you upgrade it immediately to 4GB; with the 2GB of ram you get a lot of slowdowns in multitasking . Its an easy process which is detailed in the video review below.
