Chronicle Cnet Reviews, Jan. 4

The Spectre x360 has a solid aluminum body, smooth 360-degree hinges, an excellent display and very long battery life.

Higher-end screen options could limit battery life.

The HP Spectre x360 delivers a high-end, flexible Windows laptop design at a mainstream price, with a battery that runs all day.

The Yoga 3 14 has all the flexibility of past Yoga hybrid laptops, going from clamshell to tablet and back again.

The configuration options are very good for its sub-$1,000 price.

With better battery life and performance than the Yoga 3 Pro (not to mention a lower price), the Yoga 3 14 is one of the best hybrid deals around.

The Surface Pro 3 is thinner and lighter than the previous two versions, despite having a larger 12-inch display and higher screen resolution.

A new kickstand makes it easier to set up and use, and the keyboard cover remains a best-in-class example.

The Surface Pro 3 is now optimized for a digital pen, which is included.

There is no pen storage, and even with better kickstand and keyboard hinges, the Surface Pro 3 still doesn’t fit perfectly on the lap.

While the new Surface Pro 3 is Microsoft’s best PC to date, it’s more successful as a tablet than a laptop replacement.

The Transformer Book T300 Chi makes good use of Intel’s low-power Core M processor, and includes a keyboard dock that works attached or remotely.

Performance and battery life is still not on par with what other slim hybrids and laptops deliver.

Some design quirks, such as a poorly placed power button, can get in the way.
