 Acer beTouch E110
Acer beTouch E110 was among the few phones that the company introduced at the 2010 Mobile World Congress.  It is squarely positioned as an entry level touchscreen Android device  as hinted by the 2.8" QVGA screen paired to a run-of-the-mill processor,  lack of WiFi and the old 1.5 version of Google's platform. Nothing  wrong with that as long as the price is right, however our review unit  came with a pretty basic Android distro that lacks some crucial Google  services preinstalled, most notably Android Market.

This might  be a true dealbreaker for you, as you may not be able to enjoy the  thousands of Android apps, YouTube, Google Maps and so on. So our advice  is to first check if the phone your provider is offering you has these  important programs and services or not. With that out of the way, let's  delve deeper and find an answer to the question "to beTouch or not to  beTouch."

The  phone is small and compact, with a comfy feeling in the hand albeit on  the light side with its 3.70 oz (105 grams). Weight is evenly  distributed, while successful one-handed operation will depend on the  size of your palms and fingers. For the most part, you'll be able to  operate the device with one hand only.

The overall shape is very similar to the one of the HTC Tattoo,  which would also appear to be its closest rival in terms of design and  specs. Despite the low price and basic plastics used for the casing (the  phone is available with black or dark blue back panels), the device is  built sturdy enough for normal use, and has no visible fissures between  the panels and the gray bezel.

The 2.8" resistive display  is one of the smallest you can find on a touchscreen device these days.  It is relatively responsive for a resistive screen, but visibility in  direct sunlight leaves much to be desired. The resolution is limited to  QVGA as can be expected for a low-end device.
In addition to the touchscreen, for navigation can also be used the circular d-pad,  which is the only elevated element in front of the device. The send and  end buttons on its sides are larger than the ones found in the HTC  Tattoo, for instance, and flush with the surface, glowing white when  pressed.  A thin touch strip in the bottom of the screen is where the  home, search, back and menu icons are located; these are well spaced and  responsive.
Volume rocker is on the right, easy to press, and the microUSB port used for charging and sync is located there as well, closed by a plastic cover . Оn the left side is  the microSD slot, where the 2GB card coming with the device is located –  no popping the battery out to swap memory anymore. There is a standard  3.5mm audio jack on top of the device where it belongs and that's all  there is around the bezel, no dedicated key for the 3MP camera on the  back where the speaker is located as well.
