Apologies for another 4 vs 8GB RAM topic but it's always helpful to get advise based on your specific requirements. I've finally managed to persuade my mum to convert from Windows, after having to send her 14" Dell laptop back after endless problems with it, and get a 13" Macbook Air instead. She definitely needs the 256GB storage so the problem is that this has already taken her over what she would ideally have liked to spend, so we are really hoping that we don't also need to upgrade the ram to 8GB. It will only be used for web browsing and for photos, probably just iPhoto organising/viewing and very minor editing. I'm pretty confident that 4GB will be fine for this but she will want this machine to last for the foreseeable future so i'm a bit worried about how 4GB will hold up in 4+ years time.
