Hi, I've recently made the decision to jump the Microsoft ship in favor of Mac. I currently have a Dell Inspiron One (23") desktop computer and a Dell Inspiron 11z (11.6") laptop. The laptop is about 4 ish years old and is definitely showing its age. The desktop is about 3 years old, and still working ok, but I'm to the point where I have most every other Apple product and want things to integrate better. (iPhone 4, 5, iPad 2, Apple TV 2nd gen). I want to replace both the desktop and laptop with one machine + 27" Lightning display. So my struggle is MBA vs rMBP. I like the rMPB for two reasons over the non-retina: weighs less and retina display. I like the MBA over the rMBP b/c it weighs less, but the con is no retina display. I've played with both at the local Apple Store. I'm a big fan of having a light and portable laptop for travel; the iPad by itself doesn't have all the features I'd want that the laptop can provide. I need MS Office software for work/school purposes, and potentially some other windows-only software which would require bootcamp/parallels, and also the ability to plug in USB devices to transfer files. So that means I can't just go solely iPad. I also want to replace my desktop computer with the new laptop, so I want to make sure I have enough computing power to cover the times when I make short videos (4-5 min in length usually, shot from my contourRoam). I don't game, and don't do other sorts of memory/processor hogging things like instensive PhotoShop work or anything like that. It's mostly internet browsing/ MS Office work, with the occasional video editting thrown in. I want this laptop to last for years, so I'm willing to load it up with as much RAM and disk space as I can for future-proofing. Does the fully-tricked out MBA meet my needs or do I need to wait for the new (Haswell) rMBP to be released? Do I need to wait for Mavericks, or are OS upgrades cheap and easy (assuming the masses here suggest the MBA meets my needs)?
