Challenging customer service folks in retail stores is pretty much shooting fish in a barrel-- sure, Apple claims to have a great retail environment, but if those Geniuses are getting paid as little as I was when I worked in retail, there's no real reason for them to know the difference between the Apple ][ and the Apple //e (that's what you have TUAW for).

Still, Laptop's writeup on their trip inside the Apple Store is pretty entertaining anyway. The Genius confirms what we all knew about the Macbook Air (it's a "supplemental computer, like, if you already have a desktop at home"), and messes up some specifics on HD-DVD and processor speed and size. My own Apple Store experience wasn't much better-- I had to explain what a KVM switch was (to switch between my Mac mini purchase and my gaming PC). But just like Laptop's experience, my person was helpful and quick, and what more can you really ask from a retail experience?

Long story short, do your research at home, and show up at the Apple Store (or the Best Buy, or the Circuit City, or wherever) only when you know what you really want to buy. The guys and girls with nametags on at the store know a lot about how to sell stuff, but they just don't get paid enough to make your choices for you.
