What would you do? Hoping to buy refurbished -- two options are 13" MBP, 2.66 Ghz C2D + 4 GB RAM... $1269. vs. 15" MBP, 2.4 Ghz i5 + 4 GB RAM.... $1529. - Never had a laptop before, only desktops - Played with 13" and 15" in store and loved small form factor of 13" - Hope to use on the go. Hoping to go to graduate school in a few years and use there. - Used to do a lot of photography, not much anymore but still need to process batches of photos occasionally. - Do not do any gaming or video work - Have 21" monitor at home, would probably use Henge Dock - Hope to keep for 3-5 years. - Would prefer matte screen, but not a deal breaker - would prefer a backlit keyboard, but not a deal breaker What would you do???
