It may seem as if Acer is all about Chromebooks these days, at least judging by its most recent announcements. Today, however, the company is putting the focus back on Microsoft's operating system, with the introduction of its new (and somewhat unorthodox) Aspire Z3-600. This Windows 8 machine is a 21.5-inch all-in-one that quickly stands out, namely thanks to its rather flexible and portable build. Aside from being able to quickly switch positions, the Aspire Z3-600 features a 1080p display alongside two Harman Kardon speakers, USB.3.0, HDMI (with MHL support) and, more importantly, a built-in battery capable of lasting up to a little more than 2.5 hours. Under the hood you'll find Intel's Pentium J2850 quad-core processor and HD Graphics, plus 4GB of RAM and a 750GB hard drive -- it's worth noting this model can't be customized, so what you have here is what you'll get. Speaking of which, Acer is pricing the Z3-600 at $779, with availability expected to begin later this month.
