+1I also bought a base Air strictly for web browsing and Aperture. For me it was a $300 swing to get a 8GB ram model since I bought it for $999 at Best Buy. If I went for a BTO, it would be around $1299.
I've been saying this for some time. Saying "It's only $100" is only true if your only buying option is through apple. Any US buyer would be foolish to buy a base model from apple.
