Yeah I also drive a PHEV and it just doesn't work if you can't charge it at home - you might as well not bother at all.
However, I think the idea going forward is that proper BEVs will charge at stupid fast rates - 150-200kW charges, giving you 200-300 miles range in just 30-40 minutes of charging.
And which point, for majority of commuters, it's not completely inconceivable that once a week you just go to a "fuel station" where you plug in for 30 minutes to fill up and that lasts you the whole week of commuting, even if you can't charge anywhere in between. We're not quite there yet, but I think that's the ultimate future.
