We have had great luck with iPad minis in Lifeproof cases, using FileMaker Pro databases for data entry. The system is extremely robust, waterproof, good screen size and sensitivity, and resistant to shocks at a price point well below most field computers (~$600 for 4g cellular model with case), although FileMaker will cost a few hundred more (to develop databases; the app is free). We get the cellular model for the on-board GPS, and generally don't get a cellular plan with it (upload through mobile hot spots on our phones). Depending on how much screen real estate you need, an iPhone/iPad would also work (with Lifeproof case). The only down side after two years on multiple projects (iPad minis and iPhones) is that we can't download data loggers that use USB/serial connections.
