A 2-in-1 laptop, also known as 2-in-1 PC, 2-in-1 tablet, laplet, tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both tablet computer and .
2-in-1 PCs consist of portable computer components within light and thin chassis, and exemplify technological convergence. They are convenient for media consumption and non-intensive tasks in tablet mode yet useful for content creation in laptop mode.
When connected to the keyboard, the display of the detachable can either be free-standing on the hinge or require external support, often in the form of a kickstand. Novel ways of providing external support include the bending frame and locking mechanism of the HP Spectre x2.
Though the keyboard is usually bundled with the purchase of a 2-in-1 detachable, it is occasionally deemed an optional accessory by manufacturers in order to minimize the starting price of a device. In such cases the 2-in-1 detachable is often displayed with its complementary keyboard in advertisements and promotional materials. This is true for all devices of the Surface and Surface Pro lines.
Operating system such as Android even show the mouse cursor when connected to a mouse, where as Ubuntu Touch take it even further by allowing the user to modified the UI to a typical desktop mode with window which allowed desktop level multitasking, albeit with smaller screen.
While 2-in-1s fall in a category distinct from laptops, they loosely parallel the traits of the Ultrabook device category, having light and thin chassis, Mobile processor, and long battery lives. They are distinguished from traditional Ultrabooks by the inclusion of a touchscreen display and a concealable or detachable keyboard.
Mainstream attention for 2-in-1 PCs was not achieved until nearly two decades later, when many manufactures showed devices, at that time referred to as "hybrid" devices, at CES 2011. While Packard Bell, Acer and HP all had Microsoft Windows based 2-in-1s by 2011, Lenovo released the well reviewed Windows 2-in-1: The X220 Tablet variant of the ThinkPad X220, successor of 2010's ThinkPad X201 Tablet. The 12-inch device included a digital stylus housed within the chassis, somewhat ruggedized construction, and a multi-touch screen with a twist and fold hinge.
Microsoft started its own line of 2-in-1s with the introduction of the Surface Pro series, the first of which was released in February 2013. It had a 10.6-inch (27 cm) display, Intel Core i5 CPU, and included the Pro Pen stylus and a detachable keyboard that doubled as a protective screen cover. In 2015 Microsoft introduced the Surface Book series, which, similar to the Surface Pro series, features a detachable keyboard cover and Surface Pen stylus.
Samsung entered the 2-in-1 PC market with the release of the Windows-based Samsung Galaxy TabPro S, which was released in March 2016. It had a 12-inch display, Intel Core m3 CPU, a first-party keyboard attachment, and a TabPro Pen. Its successor, the Galaxy Book, was released in February 2017. Coming in a 10.6-inch model and a 12-inch model, the Galaxy Book has an improved detachable keyboard and include an S Pen.
Google entered the 2-in-1 market after it announced the Pixel Slate in October 2018. It runs on ChromeOS and features a 12.3-inch display. It includes two USB-C ports, but it omits the 3.5mm headphone jack. The featured Pixel Keyboard and Pixelbook Pen are sold separately.
Since 2012, a number of other prominent laptop manufacturers, such as Dell, Asus, and Sony have also begun releasing their own 2-in-1s.
While the iPad Pro has optional Smart Keyboard and Apple Pencil accessories, Apple has yet to release a true 2-in-1 PC in a detachable form-factor and with a similar desktop OS, citing the quote below.
2-in-1s are natively supported by the Microsoft Windows, and Google ChromeOS . Various other Linux distributions also support some touch features of 2-in-1s, though they are generally unsupported by hardware vendors.
