In recent years, laptops with touch screens are gradually gaining popularity, along with the emergence of hybrid devices that can separate the keyboard for personal use like tablets and when needed. can turn into a handy laptop.
Lenovo also has such a hybrid product line called MIIX, with the latest representative being the recently introduced MIIX 3 at the end of 2014. The biggest difference of MIIX 3 over the previous generation is the keyboard. integrated into a protective cover like the Microsoft Surface accessory, so it can fold in both directions of the machine. As a result, MIIX 3 can be used as a tablet and quickly "transform" into a laptop for office work.
The device is also preinstalled with Windows 8.1 operating system with a number of improvements compared to the Windows 8 version on MIIX 2. Lenovo MIIX 3 has a retail price of 8.99 million, equivalent to a fairly configurable laptop on the market. school today.
MIIX 3 is a bit heavy, so long-term use will be quite tiring
MIIX 3 has a 10.1-inch screen, 16: 9 aspect ratio so it's a bit long if held vertically. In return, when used horizontally, especially when watching movies will "have" more eye with the tablet has a ratio of 4: 3 like the iPad. The body has a thickness of more than 9mm, thickening up towards the tail (part attached to the touch keyboard). The front of the machine does not have any buttons but only the touch screen with moderate edges. The back is made of smooth plastic material. This product only has a front camera with 2MP resolution for video calling, no rear camera.
Miix 3 has a slightly heavier weight compared to tablets, the body weight is about 550g. However, when attaching a protective cover to turn into a laptop, this machine weighs only about 1kg, equivalent to a netbook (small laptop), so it is convenient to carry with you. Using MIIX 3 in tablet mode to browse the web, surfing Facebook will take time to get used to because of its size and weight, but if you switch to laptop mode, the device quickly responds well because it's compact.
Unlike Android and iOS tablets that are often limited in connection ports, Windows tablets possess a variety of port types. Specifically on MIIX3, in addition to the familiar MicroUSB headphone and port jacks (which support OTG to connect to peripheral devices such as mice, external hard drives, USB), the device also has Micro HDMI port for exporting images. large screen or projector and MicroSD card slot supports up to 64GB capacity to expand storage memory.
The protective case is made of plastic material that is attached to the hand, anti-slip very well
The machine's keyboard and cover protection is covered with a floating plastic, helps grip grip and does not get fingerprints like the camera body and anti-slip very well. This case also has legs to support the machine when placed on the table, so it is quite solid. However, it only has a single opening angle of about 30 degrees, so it's not as flexible as a laptop.
Machine and shell are connected by magnet connection
The protective case has two mounts that are very sturdy, so users can be assured of ruggedness. Due to sacrificing for light weight, the device's keyboard / shell does not have extra features such as adding batteries or connecting. In addition, when attached to the case, the retaining cover covers the MicroSD card slot, so it is a little inconvenient to remove the card.
When attached, the MicroSD card slot is hidden
In general, if in tablet mode, MIIX 3 has the same design as other Windows-based tablets and does not have many outstanding features. But when combined with the keyboard and shell cover to "transform" into a laptop, MIIX 3 proved to be an interesting device by taking advantage of the Windows-specific operating system for mice and keyboards. The protective case also makes it easy to place the camera on the tabletop to watch movies or slide shows.
Screen and speakers
The screen of MIIX 3 is 10.1 inches wide with a resolution of 1920 x 1200 pixels with a pixel density of 218 ppi. This pixel density is quite good, not too high but still retains the sharpness when used because of the tablet you will see much farther than a smartphone. The viewing angle of the screen is relatively wide, when looking at the corners, the contrast is not much changed and the colors show up quite well. The maximum brightness of the measured screen is 243 nit, slightly lower when used as a tablet. The maximum brightness is not high in combination with the screen being glossy so when used outdoors it will be a bit difficult to see.
Since there is only one speaker, the sound when watching movies or listening to music will not "have" with laptops with two speakers
The loudspeaker of the machine has a fairly large volume enough to hear in the room about 20m2 or when the surroundings are not too noisy. But do there is only one external speaker on the left side, so when you use MIIX 3 you can see that the sound of the emitter is skewed, a small drawback compared to the current laptops and tablets usually have two speakers placed in two sides of the screen.
Performance and experience
Most hybrid products like the MIIX 3 have a modest configuration, using the optimal processor for battery life and operating temperatures like Intel Atom. MIIX 3 owns a set of configurations including quad-core Intel Atom Z3735F processor clocked at 1.33 GHz (can accelerate to 1.83 GHz), 2 GB RAM, integrated Intel HD Graphics graphics at 311 MHz (can be accelerated to 646 MHz), 64 GB of memory supports microSD external memory card up to 64GB.
This configuration is good enough for the device to run smoothly on basic tasks like text editing, web browsing, watching movies, playing soft titles and smoothly switching applications.
The game is not the strength of hybrid devices like MIIX 3
However, when you have to try with the game with a bit more advanced graphics such as Asphalt 8 or FIFA 15 Ultimate Team, Lenovo's tablet responds quite hard, especially with games using touch screen Apply or need to tilt the device. Overall, Lenovo MIIX 3 is suitable for office tasks and gentle, basic entertainment. If you want to handle more complex tasks like editing photoshop, editing movies or experiencing heavy graphics games, you will need a machine with a more powerful configuration.
Besides performance, the experience of using Windows 8.1 tablets is also very different from that of iPads or Android tablets. On the Metro interface, Microsoft and developers have provided a lot of applications designed for touch screens, but it can be said that they are not equal to the other two operating systems both in terms of diversity and application quality. .
When it comes to the desktop environment, everything is different. The touch screen does not match the very small icons of Windows, and the operation is also very different (for example, to open an icon on other sensors you only need to touch once, but with Windows will must touch twice). For ease of use, you should combine the keyboard cum cover.
The keyboard of the MIIX 3 has a familiar design from Lenovo, the alphanumeric keys are standard sizes, so it's easy to type. The armrests are just the right size, enough to comfortably rest your hands. The feeling of typing is good, although it is a thin key, but the key is long enough. For office work, this keyboard responds quite well.
The keyboard of the device feels good typing.
However, Windows 8.1 has not resolved well the combination of virtual keys and physical keys. In Metro interface, if no hard keys are attached, the virtual keyboard will automatically show up whenever needed; however, in the Desktop interface, you have to manually click a button on the Taskbar to turn on the virtual key, not very convenient.
However, the touchpad is a bit small and supports multi-touch not good
The touchpad on this keyboard is quite small but sensitive, supporting multi-touch but only good for page scrolling. With gestures such as finger drag to zoom in / out, the touchpad operation is not as smooth as using the touch screen.
In actual use, the lack of USB ports is also a drawback of MIIX 3, since you cannot plug in mice, USB 3Gs or external hard drives without additional accessories. USB OTG extension cord can meet this need but not very handy.
Lenovo also preinstalled some of its applications such as SHAREit, VeriFace Pro, Telegraph for Lenovo or McAfee LiveSafe security software. The number of pre-installed software is not much and if you don't need it, you can also remove it easily.
In terms of battery life, the test turned on a movie with HD resolution with screen brightness at 70%, keyboard and connections turned on, MIIX 3 ran the movie 5 hours 45 minutes, the device was nearly empty battery and turn itself off. Thus, if the need to use with intensity is not too high, the battery of the device is enough for the day. CThe original charger of the machine has 1.5A output current compared to tablets usually 2A so the charging speed is quite good
slow. When testing the charger from the status of the device is turned off to protect the battery (about 3% of the battery), after 5 hours 30 minutes the device is full of battery.
With the keyboard and cover protection, MIIX 3 has well integrated the advantages of both tablet and laptop when users can both use the device as a tablet and switch to work as a laptop when needed.
MIIX 3 will be suitable for those who love the compact, handy touch screen of the tablet but still need to work on Windows environment, especially to have a hard keyboard for quick and convenient data entry . However, hope is also Lenovo will improve performance for the next MIIX 3 versions to better meet the needs work, entertainment and games.
