The Acer DX650 has debuted in the Philippine Windows Mobile market with a unique dual-sided design. Although it wasn't announced during the MWC 2009
, it seems that it has been prepared a long time ago, as it uses the old Eten's personalized interface instead of the newer one we saw at the show. However, key feature is the design - on one side, you have a full touchscreen with two hardware buttons. Flip the handset around and it reveals a numerical keypad with a small black and white screen. The idea behind the small screen is to improve upon the abilities of a Windows Mobile device by putting what would be considered a low-priced phone
on the reverse of the high-end touchscreen to make sending and receiving texts easier. Contacts, call histories and SMS can be viewed on both sides. One problem with this idea is that the small black and white screen might be too small to use for reading words and numbers. Texting using the numerical keypad is helped with the default setting of predictive text, using the # key as a space bar. There is also a jog dial on the side of the unit that allows for vertical navigation. Horizontal movement is not yet supported although that can be fixed with a firmware upgrade. The device is equipped with a 2MP camera, GPS, 3G connectivity, Wi-Fi and a microSD slot to expand the memory. While the dual faced approach is unique, it doesn't look like something that would catch on in the States beyond being a small novelty, and in fact, there is no word on any plans to sell the device away from the Philippines. The price is 24,990 Pesos or roughly $517 US dollars.
