I suppose it's because I'm an Egyptology nerd, Brownie - but when I see a drama supposedly based on real events, I'd like at least some nod to the historical facts of the era. Still, at least there were no shots of camels climbing pyramids in the background..... 
Your last comment reminds me of a biscuit barrel my mum had for years (art deco shape), which had camels and pyramids. It was lovely really, she gave it to me and I broke it

.
During the show, my husband did say at one stage, "Why doesn't he get out his mobile?".
Sometimes I think the producers might as well have stuff like mobiles, yellow lines, Concorde going overhead and other anachronisms in period drama, it could be fun and at least no-one would be spotting the anachronisms.
(My old man is a petrol head and always picks up on cars from the wrong period, maybe with inaccurate number plates. Whenever a car appears I wait for the comment. Son does the same with musical instruments.)
