I know most come to the forums because they have problems they are trying to solve...
I purchased my NUC6i7KYK in January of 2017. I absolutely love it. I run Windows 10, with 8GB of RAM and a 512 GB M2 storage. It's been awesome. Boot-up time is amazing, and the performance has been fantastic for what I do. Typical usage is Office documents, browsing the internet, and Lightroom for managing a library of 15,000+ pictures.
This is my first "mini computer". I've built and used computers since my first Coleco ADAM computer back in 1983... I wasn't sure what to expect from this NUC but I can say I have zero complaints!
