The battery in this new Sony Vaio Z was even better than in the previous version, clocking in at 5 hours and 4 minutes (versus 4 hours and 30 minutes in 2011). It also ran longer than ultrabooks such as the Lenovo U300s and Acer Aspire S3, but not as long as Apple's 13-inch MacBook Air or Samsung Series 9. But, when attaching the secondary slice battery, the system uses both the internal and slice, and runs for an impressive 10 hours and 29 minutes (note that our battery life comparison charts include the internal battery score).
The Sony Vaio Z is backed by an industry-standard one-year warranty, although for $2,000 we'd expect two or three years. You can upgrade to a two-year plan for $179 or add a third year for $249. Support is accessible 24-7 via a toll-free phone line, an online knowledge base, and a Web site with driver downloads. Sony's support sites are clean and easy to navigate, but information about your exact laptop configuration may be hard to find.
Prior to ultrabooks, the Sony Vaio Z was an expensive, but not unthinkable, bit of executive flash. The hardware and extras, including the unique external GPU dock, are still impressive, but with thin, upscale 13-inch laptops hitting $999 or less, the audience for this has shrunk to only those who absolutely need the extra graphics power.
