Sure, it’s not all about specs. But certain things need a bare minimum even at the entry level. Would it be fair to say 1GB RAM, that was something from 2015? 2GB must definitely be minimum for 2016 let alone 2017.. I picked up a Blu Life Mark so that my sister had some kind of Pokemon Go thing. That basic Android has 2GB RAM (and works surprisingly well).
Apparently the E1 might also be known as a TA-1000. Certainly no terminator.
I’d expect something like this to come out around 50GBP if these are the specs they’re offering.
