Mini ultrabook. A handy 11.6-inch notebook with a low-voltage Core i5, USB 3.0 and HD 4000. The Aspire costs significantly less than an entry-level ultrabook, but falls short of a few mobility factors.

The only thing really wrong with this is the low fidelity of the speakers then....
Have three since the introduction on the market. The battery life soon made them pointless. After some years of usage, I preserved them in proper bags in the IT storage room. 1-2 years later, after an attempt to start them, two of the three appeared to be dead. The third one worked for a while as a companion of the projector on seminars but eventually, after some months it died too. For me, this was such a waste of resources.
