The Good Beautifully designed and less than 3 pounds (1.4 kg), the HP Spectre x360 13 has a great keyboard and trackpad, a sharp 4K display and an above-average sound system. Battery life is decent for such a power-sucking screen, and performance fits right in line with its class.

The Bad Battery life takes a hit with the 4K display compared to high definition. The system runs a little hot.

The Bottom Line The HP Spectre x360 13 is a great little laptop, but if battery life matters to you a lot, opt for the HD display, not the more expensive 4K.

Thanks to a first-class execution, the HP Spectre x360 13 is the Mini-Me of its head-turning 15-inch sister. What's most surprising about it is how little HP had to drop from the design to shrink it into a 2.8-pound (1.29 kg), slightly larger than a letter/A4-sized 2-in-1 laptop, turning the x360 13 into the most compelling 4K convertible in its size class. True, the only other real competitor in that class at the moment is the Lenovo Yoga 910, but it has clear advantages over that and only a few relative drawbacks.

Of course, the first question you have to ask yourself when considering either system would be "do I really want such a small 4K display?" A lot of people don't notice or just don't mind the difference between the roughly 200 pixels-per-inch sharpness of 1,920x1,080 with the 13.3-inch display and the 331ppi of 4K UHD. I do. Interface text is easier to read, and I can really judge photo sharpness. But it comes with two big tradeoffs: battery life and price.

The 4K model's battery life tests out about 14 percent shorter than the close-to-identical HD model we tested last fall, dropping from about 9.5 hours to 8. (The 4K model uses newer DDR4 memory which operates at a lower voltage and thus gives back some battery life, which makes the gap less extreme.) However, that's comparable to a similarly equipped 4K Yoga 910. And HP rates the battery life at 16 hours for the HD model against 8 for the 4K -- that's a nontrivial difference. The larger model comes with a choice of a higher-capacity battery to compensate, a luxury this model doesn't have. Plus, it can run a little hot when there's no airflow around the bottom.

As for price, you're paying a $250 (or a whopping £400) premium for the glory of 4K. Given that the display has a relatively small color gamut -- not even 100 percent sRGB -- you're not even getting top-of-the-line 4K for watching movies. Granted, the 4K video looks good and streams smoothly, but it's a bit too high contrast for my taste, with clipped shadows and oversaturated colors. Once again, though, a lot of people prefer that look.

Once you get past those hurdles, however, the Spectre x360 13 laps the course. It has an excellent keyboard without the layout gaffes and connection compromises of the Yoga 910. That model's awful right shift-key size and placement is a deal killer for me, and the x360 has two full-capability USB-C/Thunderbolt ports in addition to the single USB 3.1 Type A for charging devices while the laptop is powered off. You do lose the SD card slot and HDMI connector in the 15-to-13-inch downsize, but that's par for the course.

And it comes with a pleather sleeve which has a slot for the bundled Active Pen, a nice perk, if not quite as pretty as the system.

This size is more comfortable to use as a tablet than the larger models. The hinge has good tension, and though I've read complaints about position of the speakers when in "tent" mode, I had no problems hearing the audio while streaming video all night that way. Windows did seem to get stuck in tablet mode more than I like, but that's an easy fix.
