I've got two Windows 10 devices currently in use.
1. Lenovo ThinkPad X230t
2. Nokia Lumia 730 (I would like to upgrade it to a device with 2 GB RAM, but the Lumia 950 is too large for a phone in my opinion)
I've got three more devices running Windows 10 Pro, but none of them is currently in use: Lenovo ThinkPad X230, Acer Aspire One 725, Sony Vaio VPCF13E4E
Oh, and I own two Android phones at the moment: bq Aquaris X5, Samsung Galaxy S3
I like the freedom Android gives the user (sideloading applications, independence from so called "App Stores", etc.). But Windows 10 Mobile is less cluttered and has some nice features (e. g. live tiles).
