So I've decided on 2.8 15 inch macbook pro with the only upgrade being the $45+ for the 7200 or is it 7400 rpm thing for 500 gb hd. My last questions are: one- my mom wants me to ask my cousin to purchase it for us cause she lives in Virginia and we live in California; and if you didnt know the tax in Cali is high. Is thisi worth it/does it matter since I might be purchasing it over the internet. Also do they hold the model i want in stock in some apple stores? Lastly, we have to purchase iWork correct? And is mobile me worth it - i do have an iphone, and I'm confused about the preinstallation options when you buy a mbp.
