The Intel Atom Z3740 has 2 GB of RAM to the side, which is sufficient. Available is the device in four versions: 32GB eMMC, 64GB eMMC and with and without 500 GB HDD in Tastaturdock. If the keyboard is disconnected (tablet mode) is the optional HDD is not available. Programs you should not install them therefore. Since the memory card slot is also connected via USB 2.0, this is a factor of 5 more slowly than the internal eMMC memory. As this is, however, filled in the 32 GB variant already two-thirds from the factory with Windows, Recovery, etc., I have urgently advised to purchase one of the two only slightly more expensive 64 GB variants and by no means the 32GB versions, the revenge else after a few weeks or months with the next Windows updates.
In addition to the Transformer Book Asus are the Aspire switch 10 of the Acer and Lenovo Miix 2 two very similar devices available. Both are available with a seemingly better processor (Z3745), which is however not quicker. Only the graphics core is a little bit faster. In addition, the Lenovo has a higher resolution and also much brighter screen. Unfortunately for me 2 of 3 Lenovo Miix are 2 arrived defective. Even the working unit had left a good impression with an extremely stiff USB sockets and by flexing keyboard. The Aspire Switch 10 I had, however, looked at the local trade. Several issued devices had a defect on the touchpad of the reports in the reviews on Amazon is reported across the board. Thus, the two major competitors from Asus Transformer Book is due to technical KO out of the race.
What surprised me the quality of workmanship from the Transformer Book, which is excellent. The keyboard is solid and beigt not substantially through the display hinge does not wobble but is tight and also the connection between keyboard and tablet is made very solid. Thanks to an arrest is the connection, if both parts are engaged, only a button with a screwdriver, so that there is no risk, both parts inadvertently disconnect, for example when carrying or moving the display. The display with its 1366x768 pixels has a good resolution for the device size. Because at a higher resolution like 1920x1200 pixels at the Lenovo can hardly operate at normal Windows programs. Although Windows can scale, but buttons and menus are not always content with scales in the applications, so that you constantly toucht next.
However, the display of the Transformer Book is not very bright. At work on the patio is hard to think. Even a normal ceiling lamp already reflected noticeably. Convincing the other hand, is the thermal design: While the Lenovo underclocks continuous load on all four CPU cores, the Asus engineers are constantly working with the 1.33GHz and did a Videkomprimierung noticeably faster. The second shortcoming of the display the power supply has to be mentioned. If the device is turned off, takes a charge over microUSB about 6 hours. If one uses the device, the battery is charging only imperceptibly. In addition, the power supply is the microUSB jack. A separate power supply connection for fast charge to charge on the go via micorUSB while retaining the option would have helped! A great advantage of Transformer Books, however, is the USB 3.0 port on the keyboard, with the energy-hungry and fast mass storage devices can also be connected. Another positive aspect is the extremely long battery life of about 9 to 10 hours at office use.
In summary it can be said that the device is well made and solid mechanics and keyboard has. The performance is good, and the device showed no errors. Only the rather dark display and the lack of rapid charge option tarnish the otherwise very good impression.
