Seen better before
Way back in 2010 I had a dual screen device that just worked - one screen was e-ink, the other a lcd. It ran an early version of android and just worked. Unfortunately it wasn't marked very well and ended up being bought out by a Russian company.
My enTourage eDGe has been in use up to a year ago when the battery gave up the ghost, there was provision for a SIM card but I never used that.
