I picked up a Windows 10 computer at Best Buy for $150 (US).
It has a quad core atom, and battery life is rated at 9 hours, 1 week on stand by.
2 GB ram, 32 GB SSD storage.
It comes with Win_8.1 with free upgrade to Win_10.
Mine is still loading updates, etc for Win_10, so I have no hands-on experience to report.
I did notice that it is infested with bloatware, so after the updates drizzle in, I'll put on the hip boots and wade in to see what I can remove.
Looks like it's OK for Internet browsing, and word processing, maybe book reading, etc.
Don't expect to edit video.
Best,
