A side effect of this is in the mornings, when most traffic is from stations towards the city centre, there are no bikes at stations; and in the evenings, when most traffic is from the city centre towards the stations, there are no free return spots near stations. To compensate for this, lorryloads of vans shuttle back and forth in the opposite direction to the commuters.
Obviously, zipcar would follow a different demand pattern to a bike hire scheme, but there's still a risk there'd be large scale patterns in demand - for example in the holiday season all the zipcars might get driven to the airport.
That isn't an insurmountable problem, of course. Presumably Avis deal with this every day. But presumably they don't plan to turn Zipcar into Avis.
"See, Paris has a handful of steep hills. The Montmartre neighborhood, for example, is perched at the top of a rise some 450 feet above the Seine. Taking a bike down the hill has a certain obvious appeal, but riding back up to the top... not so much."
"Over the summer, though, the good people of Vélib added a simple behavioral incentive to the system: Return your bike to one of 100 stations perched over 60 meters above the rest of the city, and 15 minutes of free riding is added to your account."

I think it's neat they managed to put some game mechanics in to the pricing model to encourage users to make the whole system work better for other users.
The Barclays Bike Hire coverage is good in central London but not good for the 'burbs. I'd consider using one every day for my commute however:-
* my commute would be right on the edge of 30 minutes (it's ~8 miles) and those bikes aren't the fastest (but that's good for training!). To be safe I'd have to break it up into two journeys with a 5 minute break in the middle to avoid being charged for £1 a usage on top of access. Or I can split it up into a cycle and then a run (good except that I sometimes I have to lug my work laptop with me which isn't idea for running).
* even with the upcoming (Spring 2014) extension to SW London I'm still going to be a 5 minute run from the nearest bikes. Right now it's a 4 mile run to the nearest docking station.
* no way to mount panniers, limited carrying space in the front 'basket' area, for bigger loads I'd need a rucksack and I much prefer panniers to a rucksack
£90 for annual Barclays Bike access (and no hire fees) is roughly comparable to the wear and tear costs for my current bike (~4000 commuting miles a year, proportional costs for brake blocks, chains, chainrings, sprockets, rims, hubs, bottom bracket, [carbon] forks). It's certainly cheaper than ~£900 for the annual train ticket.
Not having to worry about theft is a major plus, nor is having to carry good locks to lock up the bike should I have a mechanical that I can't fix quickly (I do the nursery run so I can't be home late).
I would also be helping the distribution problem as I'd be dropping off a bike near a major rail terminus in the morning, and using one from there to go home.
I agree with others here: desolate stations could be refilled via economic incentives for riders.
Solution seems straight-forward to me: if you park at an empty rack, or if you take a bike from a full rack your trip is free (if you are casual user) or you get small amount of credit (50p?) if you are a subscription user.
My experience with cyclehire though is they always choose the most complicated path. As an example they way over engineer their authentication. Besides a password you have to answer several security questions. Feels so disproportionate.
Regarding complication of hiring Boris Bikes, note that if you want to do a one-time (without an existing account) hire of two bikes, you need to insert and remove your credit card 4 or 5 times, and will get two or three pieces of paper out! The UX is just insane.
According to [1] they have a fleet of 14 electric vans (pulling trailers of 20 bikes), 10 diesel cars (pulling the same trailers), 7 sprinter vans (16 bikes) and 3 DAF 7.5 tonne trucks (50 bikes each). But that fleet is to deal with peak demand, such as during tube strikes.

Better let them know it's not possible to avoid returning cars to their place of rental yet...
It's more expensive, the cars are all smart cars, and you have to leave the car within a home location.
