It's not hard to install it, but it's not very usable as a phone yet. The software runs but I haven't tried anything exciting like phone calls, texts, or anything like that as I don't have a sim to fit that slot. The keyboard doesn't show up for some apps, no app store, etc. It's certainly a work in progress!
I'd recommend waiting a bit longer if your loved one isn't very Linux savy. If they love to hack on Linux, it's super fun!
Mostly an instance for friends and family. Nothing special.
