I own a iMac 27" 2011, and an Macbook Air 13" 2011... I want to purchase a DSLR camera and Photoshop Lightroom 4. I plan to either go on vacation with my 12 year old to Universal Orlando & Island of Adventure & Wet N WIld & the Magic Kingdom in Florida or I was going to give my Macbook Air 13" to my son and purchase a new MacBook Pro 13" so I can put the Photoshop Lightroom 4 on my new Macbook Pro 13".. Should I purchase the new Macbook Pro or should I take my 12 year old on vacation in Orlando? (We went on vacation and did all, and I mean all of the Theme parks in California about 2 years ago, Disney Land, Disney Land Adventure, Knotts Berry Farm, Six Flags Magic Mountain for 2 days, Universal Studios, and Santa Monica Beach) Please help, Oh and even If we don't go to Orlando and I purchase the MacBook Pro, I'm still gonna take him to Wisconsin Dells this Summer...
