Bottom line	The Acer Aspire S3 is the closest you can get to the look and feel of a MacBook Air for less than $1,000, but it requires a few compromises.	The Asus Zenbook UX31E is an excellent-looking Windows Ultrabook laptop that matches the MacBook Air step for step with an even better price. Fans of great audio, high-resolution screens and lots of ports will be happy; keyboard/touch pad aficionados will be disappointed.	The latest version of the 13-inch MacBook Air vastly outperforms its predecessor, and can finally be called suitable for mainstream use, instead of relegated as a niche product.	Lenovo's stylish U300s Ultrabook is one of the best-looking Windows laptops we've seen and matches Apple's MacBook Air nearly spec for spec. The entry-level version is $100 less than Apple's, but that discount vanishes on the higher-end model.
