I write in praise of this laptop, for the money spent, its specifications far outpace anything out there. One brief comparison. For the same amount of money that I spent here at Amazon, Lenovo offered a 15.6" laptop with a dual core processor and 2 GB of RAM; compare that to this machine's quad core processor and 6 GB of RAM! Indeed, to get a machine with comparable specs, I would have needed to spend $200 more.Besides specs, the machine is flawless in operation. When I first plugged it in, the first decision I needed to make was whether or not I wanted to upgrade to Windows 10 from 8.1. Since I have been a part of the Beta testing program since its inception, for me, that was a no brainer. The upgrade went smoothly, with no warnings or glitches during the upgrade, which took less than an hour to complete.Besides text work and illustrations, my most frequently used programs are high-end photography programs, including many of which tend to be high users of memory such as Photoshop and the Franz line of products from Europe. All of these programs run very well under Windows 10, and this laptop has yet to object to anything I've thrown at it. Heck, even the audio quality is good, no doubt due to its Dolby stereo component.Could this laptop be improved? Sure, throw in a SSD and its speed will be bumped up significantly. Which points out another great feature of Lenovo computers - they're very easy to upgrade. Turn the machine over and memory and hard drive access doors are easily viewed, opened, and components upgraded or repaired.As I said, I write in praise of this laptop. I'd easily recommend it to a friend, and couldn't be happier with my purchase.
