I want to get an 11" MBA as a complement to my iMac to use when I want to escape from the home office and for (non-business) travelling. Basically I think I'd be using it for surfing the 'net and word processing, though I also want my iTunes and iPhoto libraries available. I've never owned a laptop before so I apologize if the following questions are obvious to experienced users. 1. How much RAM and storage space should I be looking at? Would the 2GB/64GB suffice or should I go for 4/128? Money is definitely an issue. 2. Will I need the external Superdrive? 3. Should I get the AppleCare? 4. What's the easiest way to transfer my current files from my iMac? I do have Time Machine set up and used it last time when switching Macs but I don't want all the stuff on my iMac going to the MBA. 5. How do I keep the iTunes library updated when I get new content? Is that where Home sharing comes in? 6. If there any point in waiting for the rumoured Sandy Bridge update or just go for the current model? Many thanks in advanceI really do appreciate your help.
