A number of hardware and software features have helped crank up the hybrid's performance. HP has put in unique Wi-Fi 802.11ac antennas, sensors and other hardware specific to this hybrid, and had to work with Microsoft to create a customized Windows 8.1 OS image, he said.
Sensors tell the operating system which mode the hybrid is in -- tablet or laptop -- and Windows can adjust the power and performance specifications accordingly.
The hybrid will also be ready for Windows 10 when the OS is released later this year. Windows 10 is more sophisticated in analyzing sensor data and adapting the OS to different usage models, Nash said.
An appealing feature in Windows 10 is the ability to automatically switch between tablet and desktop user interfaces depending on the position of a device. The hinge on Spectre X360 has a sensor that could feed data to Windows 10 to let the OS determine if the hybrid is in tablet or laptop mode.
The Spectre X360 won't win beauty awards, but it's a solid performer. If the idea of a hybrid with a non-detachable screen appeals to you, it could be worth looking into. The company later this year will ship a model of the hybrid with a 2560 x 1440-pixel resolution. The most expensive unit with a Core i7 chip, 8GB of memory and 512GB of SSD storage will be priced at $1,399.
