We're fans of the Microsoft Surface around here, but there's no denying it's a consumer-grade device. Technical-minded folks often prefer a device with some measure of upgradeability and superior durability. If you're one, but you're keen on the whole Surface concept, maybe take a look at the newly-refreshed (and unfortunately-named) HP Pro x2 612 G2. HP is showing this highly-extensible Windows 10 detachable PC at the Mobile World Congress.
The Pro x2 612 G2 originally debuted a couple of years ago as a relatively thick and beefy solid-hinge detachable. Users apparently complained about the weight and thickness of the device, as the new version is both thinner and lighter, at the expensde of the solid hinge. The new Pro x2 still comes with a stylus, and it's equipped with Kaby Lake CPUs ranging from the Pentium models all the way to the Core i7 offerings. You get 8GB of LP-DDR3 memory, PCIe SSDs up to 512GB, 802.11ac Wi-Fi, Bluetooth, and an optional LTE modem. The tablet has a USB Type-A port and a and Type-C connector that does double duty as a charging port.
The big feature of this device, and what earns it its "Pro" moniker, is that it is fully repairable in the field. Simply remove the back panel, and all of the relevant components are available for fiddling. HP has an optional ruggedized case with its own kickstand that should offer a measure of protection from environmental hazards. Buyers can also get a USB Type-C dock that offers a USB Type-A 3.0 port, two USB 2.0 ports, an Gigabit Ethernet adapter, an HDMI output, two DisplayPorts, and a USB Type-C passthrough port for charging. A smaller "travel hub" offers VGA, HDMI, and USB 2.0 ports.
