Tell me how to drink water

Who out there has had experience with those water filters that you attach to your faucet? Does the water actually taste as good as bottled? I'd love to stop essentially paying good money to bring a bunch of plastic into my house and then have to carry it out again, but water from a Brita filter pitcher just does not taste good enough to me, so if water from a faucet filter doesn't taste any better than that, I guess I'm going to have to continue to be evil.

(I'm particularly poking cereta, way2busymom, and others who live in my neck of the woods and know what the water here tastes like when unadorned.)

To make up for this incredibly boring post, let me point you at an incredibly interesting post, from the food-meta blog Raspberry Debacle, which I love: A Sketch Towards a Taxonomy of Meta-Desserts.
