I am not at all techy. Need a tablet for DH when he's doing a big charity walk to stay connected ( he needs a bigger screen that his phone and I don't want to risk pricey iPad falling into a bog) and have settled on a Samsung Galaxy . But I cannot work out which small foldable keyboard would work. Anybody have any idea? I'm doing this as a Father's Day present from the kids. Any advice taken, I do not understand this stuff sadly my skills lie elsewhere
