Hi there, I will be attending grad school in the fall and just wondering if I could get some thoughts on whether I should purchase a MB or MBP? I'm definitely going to wait June 9th to see if Jobs has anything up his sleeve, but do you guys believe it's worth it to spend the extra money for the MBP. I use my computer for browsing the internet, doing powerpoints, word docs, and may use programs in med school for viewing photos or movies. I also would ideally like the computer to last me my 4 more years in school. Also, if I kick up the RAM to 4gb on the macbook, would that help also in making it last, or is that just a waste of money? Thanks for your help and insight!
