So long as you're happy with it in white and know where to find it in the product listing, Lenovo's decent little Ideapad 100S can be had for a reduced price of just £109.99.
The main listing is for £159.99 from a reseller, but if you hit the options below for "New" from other sellers, Amazon will pop up as an option at the cheaper price.
For that you get 32GB of eMMC storage and 2GB of RAM with an Intel Atom processor, and of course, Windows 10. It isn't perfect, but as we found out in our review it's not a bad little machine for someone looking for a cheap, no-frills Windows laptop. It even has a HDMI out port for hooking up a bigger screen if you so wish.
Shipping looks to be taking 2-3 weeks right now, but it's still a good discount on previous pricing if you're prepared to wait.
