MacBook Air refreshed with all-day battery life, available today

Has anyone posted a side-by-side spec comparison to previous version?

Here's one from the Verge's Compare builder: http://www.theverge.com/products/compare/7141/5777

CPU change (lower base frequency, but new architecture, so....?), graphics bump, (much?) better battery life, (large) bump in SSD at the same price point as last year's model. Still under-loaded RAM (4 or expensive 8GB), considering how web apps have exploded in RAM spend in recent years.
