I bought a 2010 MBA 11 at launch...base model. I'm really starting to feel the slugginess of the 2GB of RAM, and the 64 GB storage is starting to get full. I've been looking at the 13 inch MBA, and while it looks like a suburb laptop, I'd really hate to update now, only to have a really significant update to the MBA line with the introduction of the Retina display. After all, I'm a display whore. I have the option (I hope!) of swapping my GF's 2008 MacBook Pro 13 for my current Air. Yes, the resolution sucks (and the battery too I think), but I'd likely put in an SSD and 4-8 GB of RAM to make it feel a little more snappy. I think this would be a nice compromise until a Retina Air comes out. However, if there is no potential of a Retina Air next year, I might as well bite the bullet and get the current Air. It just seems like Haswell will provide a significant enough update that waiting it out will reward those who do.
