Hi all. My MBP of four years went on the fritz recently. I am looking for a new MacBook to replace it for graduate school. I will be using it for PDFs, emails, writing papers, web browsing, MS Office, taking notes, Netflix, streaming videos. No real heavy lifting and no gaming. I believe I will be taking my written exams on the laptop so I would like a laptop with a nice keyboard. Battery life is not a real problem or a primary concern for me. I am deciding between -13" MBA i5 with 256 GB and 8 GB of flash -13" rMBP 2.5ghz with 256 gb. I just want a reliable and dependable machine that I will use as my primary computer and will last me the next three four years. Are there other models I should be looking at? Thank you in advance!
