Ebuyer seem to be the only seller of these, only just released.
Seems to be one of the best prices for one with 4GB RAM.
Intel Celeron N3350 1.1GHz
4GB RAM + 32GB eMMC
13.3" LED Display
Intel HD + WIFI
Windows 10 Home
Another name for this model is the ES1-332( the ES1-331 is the model previous to this one with the older processor)
This a review, but its for one with a faster processor.http://www.notebookcheck.net/Acer-Aspire-ES1-332-P91H-Notebook-Review.186688.0.html
