Expert review by : Cisco Cheng (



Sony's TT190 laptop is tiny and full of tech goodness—but is that enough to make it worth your hard-earned money?

Weighs only 2.8 pounds. Dual SSDs. Integrated Blu-ray drive. 4GB of memory. Insanely long battery life. Mobile broadband.

Underpowered. Fresh Start option is available only with Vista Business and is a $50 "upgrade." Keyboard is too small for stubby-fingered typists. Way too expensive.

Sony VAIO VGN-TT190 review: Sony VAIO VGN-TT190



Sleek, carbon-fiber chassis; includes Blu-ray drive and HDMI port; twin 128GB solid-state hard drives, 16:9 display; excellent battery life.

Painfully expensive; faster than Atom-powered Netbooks, but still not a speed demon.

Small laptops have become synonymous with low-cost Netbooks, but Sony's Vaio TT reminds us why some ultraportables can cost almost 10 times as much (hint: the 256GB SSD helps).

Product Specifications

Super portable with an ultra sleek and sophisticated profile, the TT series is the ultimate mobile office. Weighing light, it provides you with everything you need to do business wherever you are. An ergonomic isolation keyboard with keys protruding vertically from a beautifully carved flat surface enhances looks and ease of use. Typing is more comfortable than ever with no lateral movement and the center of each key slightly indented to ensure each key stroke provides a solid and precise response. Optimum spacing between keys minimizes typing errors, especially for those with long or manicured nails. With long time of cable-free computing, the VAIO TT series offers total freedom on the move. It's more than enough for a full working day. Whether you're shuttling between meetings or on a business trip, you won't need to worry about running out of battery power.
