The only reason I’ve compared this laptop with the other two in the table, is to show that this one offers a good price-performance ratio. Otherwise, the two other machines have their own reasons (and good ones) for being slightly over priced. This machine doesn’t look as stylish and slick, there’s not much metal in construction and it is quite far from being truly portable. So clearly, aesthetics and build quality have a lot to do when it comes to laptops. And if one brand has a larger fan following than another, then it’s a different ball game altogether.

ATI Mobility Radeon HD 4670: Higher clocked version of the Mobilty HD 4650. Supports the Avivo HD technology. The performance of the cards depends on the used type of memory (DDR2, DDR3, GDDR3 possible) and should lie somewhere between the desktop HD 4650 and 4670.
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.
720QM: The Core i7-720QM is the slowes Core i7 Quad Core in 2009 and clocks between 1.6 and 2.8 GHz (due to the Turbo Mode). Therefore, it combines the advantages of a slow quad core CPU with a fast single core one. Compared to the faster Core i7 mobile CPUs, the 720QM only features 6MB L3 Cache.» Further information can be found in our Comparison of Mobile Processsors.
15-inch display variants are the standard and are used for more than half of all laptops.
The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, often allows high resolutions and thus offers rich details on the screen, yet does not consume too much power and the devices can still be reasonably compact - simply the standard compromise.» To find out how fine a display is, see our DPI List.
With this weight, a laptop is rather heavier than average. Devices in this range shine more with screen size and performance than with mobility.
