We've looked at about a half-dozen Ultrabook devices here in the CRN Test Center, and Dell's XPS 13 is the cream of the crop. It's super-fast, wafer-thin, light as a feather, and is ready for business the moment its user is.
The XPS 13 also reportedly delivers about five hours of on time from a single charge but did less well in our tests. Still, the XPS is what a laptop should be. It also compared well to another Untrabook device we liked -- the Acer Aspire S3 -- and is sure to give the laptop industry a shot in the arm in 2012.
