Funnily enough I followed the Nexus 7 with a Samsung Tab A 10.1 and that also became an almost unable laggy mess in short order. The iPad mini bought around the same time as the Nexus for my wife if still going fine, as well as my grandmother's iPad. As much as I don't want to this point I think if I ever need a tablet again (I do like them for PDFs and schematics, but I have never found a good way to send and organise files for quick access that makes it worth it), I might just forgo Android tablets and go to the dark side.
