Actually, that is probably the only anti-glare unit you can find in an Apple store. When I was calling around looking for MBPs, I was always told that the anti-glare units in the stores are the maxed out units. 2.5GHz, 750GB, etc. Same for the 15" and 17". I called five different stores between where I lived and where I was headed, and all told me the same thing, even checking their stock. Since I wanted anti-glare, but not a maxed out unit, I ended up ordering online.
IMHO, the $240+ for 0.1GHz of processor speed is nuts, but if you have to have the best, there it is.
Also, I don't think the hard drive is going to be 7200rpm, but I could be wrong. On the maxed out units I was told about, it was 5400rpm. I wonder why since they max everything out, why they don't slap SSDs in them.
