Hello, I am working on a project to equip 40 field staff with a communications device, for telephony and some basic excel and presentation use. It must be a Samsung (company policy), be handy for making calls (ie not too big), and should be robust and ideally have an external keyboard. I thought about the Galaxy Tab 3 (phablet) with an Otterbox case, and am now looking for a suitable keyboard with a cable (not blue tooth). Does anyone have any suggestions or experience with this? Fiddly things like Stylus are not really suitable as they will get lost and break. All comments / advice on the choice of device and keyboard gladly received.
