Are detachable computers the best of both worlds?

Are detachable computers the best of both worlds?
Welcome to a laptop battery specialist of the HP Battery
This was the vision: that somewhere between a laptop and a tablet there would be room for the perfect Web-surfing, movie-watching, clothes-shopping, game-playing, e-mailing, social-networking, document-producing device.
It would be a chameleon. On your desk, it would have a keyboard and trackpad, as well as a processor and an operating system powerful enough to run full-featured software. For Web-surfing on the couch, the keyboard would fold away or detach, leaving you with a touch-friendly device that turned on instantly and ran your favorite mobile apps.
The first of those devices arrived several years ago, but the category got a boost in 2012 when Microsoft introduced the Windows 8 operating system, which runs on desktops, laptops, and tablets with battery such as Hp 342661-001 battery, Hp pavilion dv6000 battery, Hp Pavilion dv8000 battery, Hp HSTNN-DB20 battery, Hp 395789-001 battery, Hp 396008-001 battery, Hp Pavilion dv9000 battery, Compaq Presario V2000 battery, Hp pavillion zx5000 battery, Hp EV087AA battery, Hp EX942AA battery, Hp Pavilion ZT3000 battery. The company launched its first generation of Surface tablet computers at the same time.
Two years later, Surface is in its third generation, and it’s in competition with a range of hybrids from Lenovo, HP, Asus, and Toshiba. They come in various configurations. Arguably, though, the most interesting devices have keyboards that detach completely when you want the portability of a tablet. In recent testing, we tried to get at just what the perfect detachable computer would do—and whether ordinary people like what’s out there now.
So far, manufacturers have been more enthusiastic than potential users. In a recent survey of 1,431 readers by the Consumer Reports National Research Center, only 2 percent of respondents said they had bought a laptop with a detachable screen that could be used as a separate tablet. Perhaps people don’t care for those devices, but it’s equally likely that they’re just confused.
It’s hard to know what to make of a device if you don’t know how to classify it. Are they laptops that can pinch-hit as tablets when you don’t need the extra bulk? Or are they tablets that can step up to do a full computer’s job when asked to? And if they can’t do all things equally well, which compromises are worthwhile in the pursuit of computing versatility?
There’s no clear answer, at least not yet. That’s why we tested each device twice, once as a laptop and once as a tablet. (The results can be quite different.)
And to get at that question of what detachables are really for, we decided to ask a number of ordinary people what they thought. We put some of the models we tested in front of electronics users who said they were interested in a hybrid. They tried them in our labs and at home, performing a variety of tasks. Then we posed a simple question: “Is this machine right for you?”
