I'll be visiting Dubai next month and plan to pick up a MBP while I'm out there because of the 15% saving. This will be my first Mac and I'm not 100% sure what model to go for. It's really a flip between the 13" retina MBP and the 15" classic MBP. Which would you recommend for someone who's main usage includes social networking, uploading and editing photos, Internet and video streaming? Don't plan to travel much with the MBP so portability is not really an issue for me. I'm swayed to the 13" for the retina display and flash storage. But the 15" for bigger screen and quad core processor is attractive to me also. 1.In reality, which one would perform best for my usage? 2. Is a smaller retina screen better than a bigger and higher resolution screen? 3. What would be the differences between a UAE MBP and a UK one? Eg.Will it have a US keyboard 4. If I chose the 15" MBP and upgrade to flash storage can this be done straightaway at the store?
