The Acer Iconia Tab A100 is one of several 7″ Android tablets to hit the market in 2011. Like its 10″ cousin, the Acer Iconia Tab A500, the A100 has a stylish exterior, dual-core processor, two cameras, HDMI out, expandable memory support, and comes with Android 3.2 installed. But, The smaller version has a 7″ touchscreen display (1,0240×600).

As of this writing, the A100 is available in 8GB ($329.99) and 16GB ($349.99) versions. The current versions only support Wi-Fi connectivity. But like the A500, there is an empty spot inside the A100’s case and on the motherboard for a cellular card. The A100 weighs 0.92 lbs. and measures 7.7″ (W) x 4.6″ (H) x 0.5″ (D). It’s lighter than the HTC Flyer and BlackBerry PlayBook.

Unfortunately, the A100’s similarities to the A500 aren’t all good. Like the larger tablet, the A100 has a rather jumbled internal hardware layout. And given the A100’s smaller case, Acer crammed a lot of tech into a tight space.

Cracking Open observations

  • Easy-to-open case: There are no external case screws on the Iconia Tab, but the back cover was surprisingly easy to remove. Using a thin metal or plastic blade, I was able to quickly pop off the cover.
  • Standard screws: Inside the Iconia Tab A100, Acer used standard Phillips screws to hold the internal hardware in place. I remove all the internal screws with a Phillips #0 bit.
  • Battery can be replaced: The A100’s 1530 mAh Li-ion battery is easy to remove and replace.
  • Display is stuck to the front panel: The digitizer (front panel) and LCD screen are held together with strong adhesive.
  • 3G-ready motherboard and case: As they did on the A500, Acer left open spots on the motherboard and inside the case for a separate 3G card. The internal mounting plate even has a screw hole for the card.
  • Cramped, convoluted interior hardware layout: The A100’s internal hardware layout is extremely similar to that of the larger A500. Acer placed the u-shaped motherboard at one end of the case and the battery at the other. A small circuit board is located below the battery and connected to the motherboard via a ribbon cable. Wires are placed haphazardly around the case and secured to the surrounding components with tape.
