The Windows family has generated one of the best laptops in the market in recent years. Two options, HP's newest Spectre X360 and Lenovo's Yoga 910, are so close in terms of overall design that they're hard to tell apart at first glance.

Both HP and Lenovo offer high-end versions of their machines, but they're not identical in terms of their configurations. Both notebooks can be configured with Intel Core i7 processors and 16GB of RAM, but the similarities end there.

First, the Spectre X360 is limited to a 512GB SSD, while the Yoga 910 can be equipped with a 1TB SSD. HP, on the other hand, offers a Core i5-7200U option for a lower base price. The Spectre X360's USB Type-C port also supports Thunderbolt 3, while the Yoga 910's does not. Finally, the HP is limited to a 1080P display. The Lenovo can be equipped with high-resolution, 4K screen.

Where HP provides the most flexibility relative to Lenovo is in terms of low-end pricing. Thanks to the Core i5 option, the Spectre X360 starts out at $1,050 with 8GB of RAM and a 256GB SSD. Because it only offers a higher-end Core i7-7500U, the Yoga 910's base price is $1,180 for 8GB and a 256GB SSD.

Both the HP Spectre X360 and Lenovo Yoga 910 offer excellent displays with HD screen. However, the Yoga 910 also offers a 4K display that runs at 3,840 x 2,160-pixel resolution.

Both the HP Spectre X360 and the Lenovo Yoga 910 offer good battery life that should last close to, or just a little more than, a full day's work. The HP offers a 45-watt battery compared to the Lenovo's 66-watt option.

Both the HP Specter X360 and the Lenovo Yoga 910 are excellent 2-in-1 devices. For the price, which is substantially less than that of a Surface Book and Apple's new MacBook Pro, you can't go wrong with either the HP or the Lenovo.

Overall, however, we have to give the win to the HP Spectre X360 by just a hair. It's the smaller of the two machines and thus a bit more deserving of the 2-in-1 designation. It also offers better battery life, more configuration options, and starts out at a lower price point.
