MSI F Series laptops range in size from 14 to 17-inches and feature Intel's i5 processor. However, before we look under the hood, let's take a quick look at the exterior of these computers. MSI applied a lot of energy in this department -- they really wanted their F Series to have a unique and fashionable look and feel, so they covered the lid in a textured pattern of wavy tiles. To be honest, I'm not particularly keen on it -- the funky texture sort of makes the laptop resemble a fancy briefcase -- however, it does possess a pretty cool anti-fingerprint coating to help ward off oily marks.
I think it's really interesting that MSI pushed the "fashionable" angle with the F Series because where these laptops really shine is multimedia. They have some really cool technology under the hood! The FX600, for example, has a 1GB NVIDIA GeForce GT 325M discrete graphics card as well as four THX TruStudio (cinema quality) speakers.
What does this mean? Well, all of your audio and video (high definition or otherwise) will be about as vivid as possible. Furthermore, the NVIDIA discrete graphics card will leave you with power to spare should you want to take a break from watching movies to play some 3D games. I wouldn't go so far as to call this a gaming laptop, but its technology will definitely provide an above-average gaming experience for the price range.
A few other cool things you might be interested in are the built-in high-def webcam, backlit LCD screen, and HDMI output. The MSI F Series also features Intel's new wireless display (WiDi) technology -- this allows you to send HD images from your laptop to your HDTV, no strings attached. Cool stuff. The downside? F-series laptops get extremely average battery life, so you should probably stay close to a power outlet.
Long story short: MSI F-Series laptops are powerful, unique looking, and get better performance (especially in the multimedia department) than many of their competitors in the $800 price range. If you're interested in one, check out the 15.6-inch FX600 model.
