Toshiba's Portégé Z20t is an ultraportable laptop/tablet hybrid, one of the new breed of two-in-one systems that can be used as a slate-mode tablet or a conventional laptop.
It is also one of the early systems based on Intel's Core M platform, designed to offer increased battery life in portable systems without sacrificing performance.
Announced towards the end of last year and shipping since this spring, the Portégé Z20t is aimed at business users and professionals, a traditional market for Toshiba.
In keeping with this, the system looks smart and stylish, but also feels rugged enough to stand up to the rigours of life on the road.
For the mobile professional, the Portégé Z20t offers enough performance for business applications, and at 1.51kg, should not be too weighty to carry around.
A key feature is that the tablet and keyboard sections both have batteries, which Toshiba claims should deliver up to 16 hours of use.
In fact, the Portégé Z20t seems to be one of the most successful two-in-one designs we have seen, so those looking for a mobile business PC that blends the capabilities of a tablet and an ultraportable laptop without too many compromises should add this to their shortlist.
However, potential buyers should be aware that there are several models of the Portégé Z20t, some of which feature Intel's vPro management and security technologies, while others (such as our review unit) do not.
Some also come with a Wacom digitiser screen and stylus while others do not, and some with 3G/4G mobile broadband, while this model did not.
The design of the Z20t is quite deceptive. Unlike some hybrid or so-called two-in-one systems, you have to look closely to tell that it is anything other than a standard ultraportable laptop.
The tablet section of the system, where the guts are located, blends in seamlessly with the keyboard base, unlike so many others we have seen where the way the two parts fit together seems to have been an afterthought.
However, the giveaway is that the on/off power button is located on the edge of the screen, whereas it would typically be on the base in a standard laptop.
Much of the system I/O is also here, with the keyboard base logically relegated to having the full-size video ports (HDMI and VGA), a pair of extra USB ports and an Ethernet connector for plugging into a wired LAN.
In contrast, the tablet section sports smaller ports, including a micro HDMI, micro USB, headset jack socket and a micro SD slot for flash memory cards. It also has a power input socket on its bottom edge that is thus hidden when docked with the keyboard base.
The design of the Z20t's hinge is worth highlighting. As mentioned earlier, this mates the tablet section with the keyboard base so seamlessly that you wouldn't notice that the screen is actually designed to detach.
However, the hinge has also been designed so that opening the system lifts the keyboard up to a comfortable typing angle - a nice touch.
The tablet section can be docked facing in either direction, so that the laptop can be closed up and used as slate-mode tablet with the extra battery life afforded by the keyboard section.
Alternatively, it can serve as a stand in this configuration (see picture) for giving presentations to an audience.
A sliding catch on the hinge releases the tablet when docked. It can also be locked in place using a smaller sliding switch on the side of the keyboard, which doubles as a slot for a security cable.
