Great as the potential energy from uranium is, continued use of it at its current consumption rate will get us, what, 280 years or so?

And considering that the aformentioned consumption rate is... miniscule, compared to the rest of the stuff that we burn for energy, any sort of heavy switch to it will mean that it won't be long before we'll be out. I think I've read something along the lines of "If all the energy humans consume on the Earth were powered by nuclear reactors, we'd be out of uranium in 10 years, while coal'd last us 700"

Now, if only we could get that cold fusion thing going...

Uranium is not as rare as you might think. The US has actively worked to limit research and implementation of fast breeder reactors (using abundant U238), since they produce weapons grade plutonium. So, all the tons of U238 are processed to extract the fissionable U235.
