Reviews for the Sony Vaio VPC-Z21V9R/B

It goes without saying that $2,749 is a lot to pay for a laptop. And for this configuration you're looking at $2,899 if you opt for the sheet battery, which we highly recommend. For that kind of money, you could get a Samsung Series 9 with a Core i7 processor and still have enough left over to buy an iPad and a 4G smartphone. So you'll have to think long and hard about how much you want the Power Media Dock, a unique innovation that does indeed add plenty of power and support for multiple monitors. There's a lot we like about the notebook itself, too, including its bright display, fast Core i7 performance, and very light weight (even with the battery slice). However, the VAIO Z's keyboard and touchpad aren't as comfortable to use as the competition, and the fan noise can be distracting. Pound for pound, the VAIO Z is the fastest and most versatile ultraportable yet, but you'll have to make some trade-offs--and make serious money--to get one.

Intel HD Graphics 3000: Integrated graphics card in the Intel Sandy Bridge processors (Core ix-2xxx). The HD 3000 is the faster (internally GT2 called) version with 12 Execution Units (EUs).
Non demanding games should be playable with these graphics cards.
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.
