Hello, I have a laptop from September 2007. It is a Macbook Pro 15", 2.2 GHZ, 2 GB RAM. It is in perfect condition, and recently had the logic board and battery replaced. Anyway, I am kind of getting sick of it because it's quite big to lug around, and the programs are outdated (eg: Office 2004). The OS, Tiger, even refuses to connect with my iPhone 4! I also find that it's a tad slow. But it truly is a gorgeous laptop physically. Anyway, I am in the position right now of acquiring a brand new, top-of-the-line Macbook Pro 13" loaded with 8 GB RAM, a 256 GB SSD, Aperture 3, Office 2008, Final Cut 4, Snow Leopard, etc., etc. for 1900 USD. I can afford it fairly easily. Do you think I should buy the 13" laptop and sell my 15 incher? Or am I just thinking that the grass is "greener on the other side" and that I'll miss the screen space? Alternatively, for less than $600, I could upgrade my MBP to 4 gigs of RAM and a solid state drive, + buy the Mac box set. Thanks! (By the way, I was the person who posted about the Sony Vaio. I bought it, used it for some time, and returned it. I just found the small touchpad was irritating after a while).
