Note that I'm a Giants fan, but that doesn't mean I'm an anti-A's fan. I just think that the A's will be perpetually under the shadow of the Giants as long as they stay anywhere in the Bay Area, even the San Jose area, and even when the A's field a better team. They'd be better off in Sacramento, where they would be the dominant team rather than second fiddle.
The Razor & Mr. T let me make all of my points, and I think I managed to make them pretty clearly. Of course, money is the sticking point, as it is in all of these things, and I certainly don't think we'll be seeing MLB in Sacramento anytime soon.
