Detaching the display from the keyboard involves a bit of a dance, as you must first push an eject button (if there's USB storage plugged into the keyboard), then slide a spring-loaded button to release the display (I found I had to use my fingernail) while your other hand lifts the tablet out of the dock.
The display is enclosed in a stiff resin material that has a textured finish to help you maintain a firm grip. Vents on the top, right, and bottom of the tablet keep things cool. These are augmented by a small, but annoyingly loud fan; fortunately, it spun up rarely and never for very long.
Considering the dock's thinness, I was pleasantly surprised by the good feel of its island-style keyboard. Most of the short-throw keys are of typical size, but the Ctrl, Fn, Windows, Alt, Shift and Enter keys are about half normal size, while the even-less-used Function, Tab, Page-up/down, arrow, and Del keys are about quarter-sized.
This isn't a keyboard you'll want to use all day long when you're deskbound, but it's pretty good all things considered. There's a blue eraser-head pointer stick (Toshiba calls it an AccuPoint II pointing device), and a smallish touchpad on the wrist rest with mechanical left and right buttons on top and capacitive mouse buttons at the bottom.
The dock has both HDMI and VGA video connections, a gigabit ethernet port, and a USB 2.0 port. Unlike some 2-in-1 hybrids we've seen, the Portege Z10t doesn't have a second battery in the keyboard (although it does have a power socket, as does the display). In addition to the video ports on its tablet and dock, the Portege Z10t also supports Intel's Wireless Display technology. And 802.11ac Wi-Fi is provided by Intel's Dual Band Wireless-AC 7260 chipset.
Toshiba's Portege Z10t significantly outperformed HP's consumer-oriented Spectre x2 hybrid, earning a Notebook WorldBench 9 score of 67 to the HP's 50. But the HP had a lesser processor (an Intel Core i5-4202Y), half as much memory, and a much smaller SSD. The Spectre x2 weighs almost a pound more than the Portege, but most of that weight can be attributed to its larger display (13.3 inches) and the presence of a second battery in its keyboard dock.
The Portege also delivered solid scores on PCMark 8, Cinebench, the audio-editing, and the CPU-based image-editing benchmarks. Gaming performance was nothing special, but that's no surprise considering this business-oriented machine relies on integrated graphics. Battery life was a medicore 4 hours and 28 minutes. The dual-battery HP Spectre x2 lasted about 27 minutes longer.
