Reviews for the Sony Vaio VPC-Z21Q9E
Perfect shortcomings. It almost sounds like a fairy tale when it comes to what Sony has created with the new Z models: An extremely thin 13.1 inch subnotebook weighing a mere 1.2 kilograms, that provides as much performance as a large notebook, and furthermore shines with an A1 display, good battery life, and low heat and noise emissions. How this is possible? Via Power Dock and Intel Light Peak.
Sony has launched the new Vaio Z2 notebook, a 13.1-inch ultrabook with a breath-takingly sharp 1080p display and a second battery pack which can double mains-free runtime. The Sony Vaio Z2 is a mighty powerful take on the ultraportable format, and while it has very few if any weak points, its high price reflects it’s premium status.

The Sony VAIO Z2 is a series of fantastic ideas undone by a few bad ones. On paper and with the price tag out of the equation, there are very few ultraportables on the market more compelling than what Sony hopes to offer the end consumer. A beautiful carbon fiber chassis, stellar quality 1080p screen, powerful Intel Core i7 dual-core processor, excellent battery life with or without the sheet battery.

We were disappointed that Sony loads up this computer with lots of bloatware and trialware. Some of the most predominant software includes trials to Norton Internet Security and Microsoft Office 2010. Sony also installs software like PowerDVD and Skype. These programs bog down performance pretty noticeably, especially since many of them run at startup, so you'll want to spend some time uninstalling the unnecessary ones.

CommentAMD Radeon HD 6650M: Successor of the Mobility Radeon HD 5650 with more cores, UVD3 processor and Eyefinity+. Due to the same codename, the 6650M should be a HD 6750M with slow DDR3 memory. Non demanding games should be playable with these graphics cards. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
2620M: Very fast Dual-core processor based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. » Further information can be found in our Comparison of Mobile Processsors.
Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.» To find out how fine a display is, see our DPI List.
This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.
