I've got a plugin hybrid.
I love it. It has the right amount of battery for my daily commute (although in winter it likes to warm up the engine, so I do still use some petrol), and even with the cost of electricity it's still cheaper than petrol (just)
Mainly though, it's convenience - I don't pass a petrol station day to day, and being able to drive on electric most of the time means that I only have to detour once a month, and I can string it out if I need to - same if I run out of charge, I can just use the petrol.
Even if I haven't charged, just the regenerative braking means that I spend about 1/3rd of my time on electric.
There was an issue recently where the little battery (it still has a normal engine battery) was knackered by sitting in the car at piano lessons and such - but they swapped that under warranty, and it went through a host of software updates, so hopefully that won't happen again.
