Sony Vaio TZ

Sony Vaio TZ

Weight: 2.7 pounds

Price: Starting at $2,200

The Vaio TZ is sleek, stylish, and durable, and it shares many of the features with other ultraportable laptops on the market, including an Intel Core 2 Duo processor, Bluetooth technology, and support for 802.11n.

Sony's trying to make security one of Vaio TZ's selling points, incorporating a fingerprint sensor, an integrated Trusted Platform Module to control access to the laptop, and G-Sensor Shock Protection. Here's how the shock protection works: When the built-in 3-D acceleration sensor detects a risky movement, the HDD head locks up to secure its position and prevent damage to data.

On the off chance you can sneak time for a movie or some music on the road, the Vaio lets you play DVDs or CDs without booting up Windows. They're controlled with a set of dedicated audiovisual buttons.

Sony calls its Vaio TZ "an ultra-portable powerhouse," but with four to 7.5 hours of battery life, it's not going to give you the long hours away from a power plug that others will.

Weight: 5.4 pounds
Price: Starting at $1,999

The MacBook Pro has been creeping into the hands of mobile professionals who aren't typical Apple creative types. But there's a price for Apple pizzazz: size and weight, as its MacBook Pro comes slightly heavier and with a larger screen than most competitors in the ultraportable mold.
