I think plug-in hybrids are the current sweet spot for people who can charge at home (or maybe at work). The results in this article are impressive, but cross-country trips across America aren't very representative of the kinds of driving people actually do. Most trips, especially daily commuting, are short enough that a plug-in hybrid could do the entire trip on battery power and then you have the gas engine for longer distance trips where it behaves like a regular hybrid.
All-electric cars are getting closer, but the long distance driving experience just isn't as good yet as driving a gas car. But that will continue to improve and electric cars have a lot of other advantages like simplicity, so I'm fairly confident they'll win out eventually. But as you said, for at least the next decade hybrid cars occupy a pretty good niche.
