The Vaio X is the latest, and like Sony's previous Atom-powered high-concept P series, it has only one foot in the Netbook camp. Incredibly thin and light, thanks to a carbon fiber chassis and solid-state hard drive, the 11-inch Vaio X looks like a high-end ultraportable. It's so weightless that several people picked up our review unit and asked if it was a dummy mockup build, instead of a fully functioning PC.
The extreme design doesn't seem out of place for $1,499, if the performance could keep up. Instead, the Vaio X uses Intel's 2.0GHz Atom Z550, a small step up from the same Atom CPUs found in $299 Netbooks. Adding 2GB of RAM and Windows 7 helps, and the system is slightly faster than other Atom-powered notebooks we've tested, but Vaio X still offers essentially Netbook-level performance in an extremely expensive package.
