We just moved to Florida three months ago and our new home and every other I see being built are on a slab, no basements. I believe it's because of a high water table even though we're in what you might call "hill" country.
Prior to moving, we had yard sale that involved moving a ton of stuff out from our basement and a huge third-floor attic. That convinced me that basements and attics are evil. Well, maybe not evil, but good mostly for keeping stuff you really don't need. An exception, of course, would be if you live in an area prone to tornados.
Our community has a lot of tunnels for golf carts to go under roads (common mode of transportation here) and I haven't seen any water problems, even on a few just being dug, so I don't know how high our water table is. Either way, I'm glad not to have a basement.
