Reviews for the Acer Iconia B1-721

77% Review Acer Iconia B1-721 Tablet | Notebookcheck
Icon or illusion? The 7-inch Iconia B1-721 is Acer's new contribution to the tablet market's 200 Euros (~$275) price class. Its driving force is a 1.3 GHz MediaTek MT8312 alongside an integrated Mali MP400 graphics chip. 1 GB of DDR3 RAM, 16 GB of flash storage and 3G wireless complete the package. But the display only offers 1024x600 pixels. Is that still enough for the tablet to hold its own in the entry-level class?

The Acer Iconia B1-721 is a budget 7 inch device with decent functionality. The gray casing gives off a nice elegant vibe while the ribbed backside makes the phone feel good in your hands. Sadly, the phone does feel a bit weak as it can be bent easily and makes creaking noises when twisted too much. Nonetheless, unless the intention is to break the device, it should not give in under normal usage.

The Acer Iconia B1-721 is powered by a MediaTek MT8312 dual core processor with a frequency of 1.3 GHz. Along with 1 GB of RAM, users will be able to browse the internet, play games and keep update on social media without many lags. It comes with 16 GB of native memory and has the option to upgrade with a micro SD card.

The 7 inch display has a low resolution of only 1024 by 600 pixels. However, for a budget device, one shouldn't be expecting a high resolution display. Still, the display is good enough for reading moderately sized text.

All in all, the Acer Iconia B1-721 offers a cheap price tag to own a 7 inch tablet with good functionalities as well. It won't be able to match up with other flagship models, but will give casual users a good run for their money.

ARM Mali-400 MP: OpenGL ES 2.0 graphics card for ARM SoCs that is scaleable from one to four fragment processors and has got one vertex processor. Mainly used in conjunction with ARM A9 cores in tablets and smartphones.

Only a few smartphones have larger screens.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

This weight is somewhat high for a smartphone. Smartphones with a big screen and small tablets weigh as much, usually.

Acer: The company was founded under the name of Multitech in Taiwan in 1976 and renamed to Acer or Acer Group in 1987. The product range includes, for example, laptops, tablets, smartphones, desktops, monitors and televisions. Gateway Inc. and Packard Bell also belong to the Group and sell their own laptops.

While Acer still had the third largest global market share in the notebook segment in 2008, it ranked 6th in 2016 with a market share of 6% after they had continuously lost market shares.

There are dozens of Acer laptop reviews per month, the ratings are average (as of 2016). Gateway, which has an own laptop line-up, has also belonged to the Acer Group since 2007.

77%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
