While the Microsoft Surface tablet being used for the test is the RT variant with an ARM supported processor, Democracy Live CEO Bryan Finney says that he will talk with Microsoft about using more Surface tablets for future elections and would like to use the Intel powered Microsoft Surface 8 Pro model. The test in Virginia is to get feedback from those who get to use the device.
Current computers in polling places are older machines with outdated specs which makes the speed of the tablet stand out. By time of the next presidential election in 2016, the speed of electronic balloting could be blinding. Consider where we were with mobile device speeds in 2008 and where we are now.
