It's not just the range that keeps me from considering an EV - it's also the ease of quickly extending that range.
My car has around a 450 mile range on gas. If I drive 400 miles, I can stop at any gas station and fill up to get another 400 miles tacked on. Rinse and repeat - I can go across the country and back as long as I have the money to do it. More realistically, I can completely change plans and drive to and from a new area without worrying about getting stranded.
With an EV, I have to hope to find a place to plug in, and then wait for the battery to charge sufficiently (versus 2-5 minutes flat to fill your gas tank). If my plans change AGAIN and I find myself driving another 30 unexpected miles, I have to do it all over again. There's a lot of hope and prayers in that situation that you wouldn't even consider driving a normal gas-engined vehicle.
If we had quick charge stations even 1/10th as common as gas stations, I'd consider it. For now, it's just not feasible for me.
Just got back from my first road trip in a BEV, 800+ miles round trip in my friend's Model S. While I am usually a road warrior and try to put 300 miles under my belt before a stop, I was pleasantly surprised how well it went with the superchargers and we traded stop time for numerous stops. The longest we were at a charger was around 45 minutes, which aligned with a good time to get a proper sit down meal on the way there and back.
Only one leg of our trip did we run into range anxiety, and even that was easily fixed by driving slower, which is hard to do with a P85D.
I agree it is not as convenient as just gassing up and going, but we essentially made our trip for free, as we were not in a huge hurry. Got stuck in a traffic jam in Maryland, and it was brilliant to not be cooking brakes and instead recouping some of the lost energy.
Tesla makes it much easier to plan your route, since the in-car nav system knows where the superchargers are, and it's UI is superior to any system I have used.
While this next shift, which is definitely coming, basically revolves around the battery, there is no doubt in my mind about electric motors having a distinct edge over Otto gasoline or Diesel cycle ICE.
We already have a way to expend the energy in a gloriously simplified way, with the added bonus of recapturing much of it, but the storage is the problem. Always has, always will be. I'm not sure of GM's intentions, and they could have massaged the EV1 and Saturn to really come out ahead in this game they are playing catch up to now. They clearly have the capital and supply connections to bring BEVs into mainstream thinking. Maybe we will skip diesels and go right to electric motors, it works for trains after all.
