The surfaces of the housing made of brushed aluminum make a very high-quality impression; the floor is made of black plastic. The instrument is ideally processed and amazingly thin and light. The keyboard is illuminated, can be operated excellently and stable, is relatively insensitive to fingerprints. Very rapid notebook that with its operating system Windows 8.1 prof. 64 bits in 12 sec. Is booted. Impressive speed with power-intensive programs such as video editing and Photoshop. The battery is built and therefore not easily replaceable! The Full HD screen resolution of 1920x1080 is just acceptable for a 15 "screen. For a 22-inch model that would be a must. The problem with such high resolutions with so large screens is the very nature though sharp but small picture. Not all applications (eg Photoshop) can be represented also by the greater possibility of scaling! A tip device if the screen would not be so disappointing poorly illuminated and even small changes in shades of view very strongly Actually from a performance point. Only in the vertical viewing the surface is illuminated reasonably evenly but even here the drop in brightness (vignetting) at the edges and corners is striking; for an IPS display completely unusual! My complaint of the defect when Toshiba service was told that this was not an IPS display! ?? Here I do not understand the unique declaration as IPS display on the Toshiba site and on most online merchants!
