Gone are the days of limited affordable tablet options. The Acer Iconia W4-821 is a stylish, simple looking device which feels good in hand. The exterior comes in brush aluminium silver with a black front border. The rear panel panel of the tablet is only accented with the Acer logo and a camera at the upper left corner. Sporting a Windows 8.1 operating system, the Acer Iconia W4-821 brings fully fledged OS functionality in the user's hand.
The hardware consists of an Intel Atom Z3740 quad core processor clocked at 1.33 GHz, 2 GB LPDDR3 RAM and an internal storage of 64 GB which is a nice size to start with. Despite the unusual huge storage capacity, Acer still provided an MicroSD card reader allowing huge amounts of portable data. The 8 inch Active Matrix TFT LCD display uses LED technology.
An Intel HD Graphics controller with shared memory powers the display. Technologies packed in the Acer Iconia W4-821 include GPS, Bluetooth 4.0, and HDMI out. The 425 g device comes with a 2 cell Lithium Polymer battery rated at 4960 mAh, which provides a runtime of 8 hours.
Intel HD Graphics (Bay Trail):

Intel Atom: The Intel Atom series is a 64-Bit (not every model supports 64bit) microprocessor for cheap and small notebooks (so called netbooks), MIDs, or UMPCs. The speciality of the new architecture is the "in order" execution (instead of the usual and faster "out of order" execution). Therefore, the transistor count of the Atom series is much lower and, thus, cheaper to produce. Furthermore, the power consumption is very low. The performance per Megahertz is therfore worse than the old Pentium 3M (1,2 GHz on par with a 1.6 GHz Atom).
Z3740: Soc with an integrated quad core Atom processor clocked at up to 1.86 GHz (Turbo), an Intel HD Graphics GPU and a dual channel LPDDR3-1067 memory controller.» Further information can be found in our Comparison of Mobile Processsors.
Large smartphones and a few small tablets are available for this display size. Unlike most smartphones, you can see more on the screen, more details and use larger resolutions. Such formats are better for people with defective vision. However, such devices are no longer easy to fit in a pocket, and they are probably not quite light either.» To find out how fine a display is, see our DPI List.
