Our users often ask us about the minimal specification for the tablets to be used with Survey Solutions. While we understand the desire to cut costs of conducting surveys, we recommend purchasing the most powerful tablets you can afford. With a very few exceptions, the total survey budget is much larger compared to the budget you spend even on the most powerful tablets. Modern tablets provide much better interviewer experience: they are more responsive and have longer battery life. What is more important, such tablets have lower per survey costs on the long run - you will be able to use them for the next two or three years in multiple surveys.
Please see the list of tablets we tested and recommend for the use with Survey Solutions.
