Acer's taken more than a passing fancy to Chrome OS of late, but at this year's IFA, the company's showing a rekindled love for its affordable tablet range. Its first new slates since the beginning of the year come in two sizes, with the more portable 8-inch form factor also offering a choice of platform. The Iconia One Tab 8 runs Android 4.4 KitKat on a quad-core Intel Atom processor (the Z3735G, if you're interested), with an 8-inch, 1,280 x 800 IPS display up front. Otherwise, it's got most of the standard features you'd expect on a tablet, like a pair of cameras and microSD slot for storage expansion. Now picture essentially the same hardware configuration, but instead running Windows 8.1 with Bing, and you've got the Iconia Tab 8 W. Successor to the Iconia W4, the Tab 8 W also boasts up to eight hours of battery life and one free year of Office 365. Whether you prefer Google's or Microsoft's OS, both 8-inch slates will launch next month in Europe for €150, and in the US in November for $150.
