I'm typing this on a 5 year old netbook that had cost me $300 back then with 2GB, which I later upgraded to 4GB. It runs Windows 10 very smoothly, it's my living room TV computer for browsing, torrenting (up to 1080p) etc. At this time I'm running Firefox, Chrome, VLC and uTorrent seeding and performance is decent, certainly not "unusable".
