At some point -- we're not sure when -- Sony's naming scheme for laptops got confusing. There was the C series and the E series. The S, T, Z and even the F (RIP). Fortunately, Sony's been working to clear things up: its first Windows 8 products all had descriptive names like "Duo" or "Tap." Now, it's streamlining its mainstream notebooks too. The company just unveiled some redesigned models for back-to-school season, and they're all named 'Fit.' As the replacement to the entry-level E series and most of the T line, the Fit family includes both lower-end models (the Fit 14E / Fit 15E) and premium ones (the Fit 14 / Fit 15). They'll be available this month, starting at $550 and going all the way up to $2,210, depending on how many upgrades you check off during the configuration process.
Regardless, there are certain specs you'll find across the board - not just on the Fit machines, mind you, but on every Sony PC announced this season. These include NFC, backlit keyboards and webcams with Sony's Exmor R imaging tech for better low-light performance. They'll all have 1080p screens, too, with the exception of the 14-inch Fits, which start at 1,600 x 900. Both the Fit and Fit E will be offered with optional NVIDIA GT 740M GPUs (1GB or 2GB), touchscreens, optical drives and a choice of Core i3, i5 and i7 processors (Ivy Bridge for now). Ultimately, then, the difference between the two comes down to build quality: the Fit E is made of plastic, whereas the Fit has a thinner aluminum chassis, with the fans hidden above the keyboard, and a lid that covers the hinge. Also, the Fit will be offered with SSDs, with hybrid drives being the base option; the Fit E comes standard with a regular HDD and can be upgraded to a hybrid drive. And in any event, all of these laptops will be available later this month. For now, check out the press shots below for a closer look.
