Ill be purchasing a Blackbook very soon and I can't freaking wait to get my hands on my first Mac. My question is as to whether or not the Apple store carries different configurations of notebooks rather than only the base versions. So will I be able to go to the Apple Store and buy lets say a blackbook with the 200 gb 7200 rpm HDD or more 4 GB RAM etc? It's not a big deal to order it online, but I would prefer to just pick it up right then and there. thanks a lot!
