Good to know that there are more Sensible folks like you out there who appreciate the work Microsoft has done and is doing in this space.
Have you had the oppurtunity to play with/work with Microsoft's Threat Modelling Tool?
In contrast Samsung has pathetic credentials when it comes to Security.
Why do you think their own Homegrown OS(in the smartphone space) is failing/ faringso miserably versus Android?
Samsung patches and upgrades Android OSes atleast 3-4 months AFTER Google releases them.
Just for fun's sake,I bought two phones with basically the same Hardware and Software(one from Samsung and the other was Stock Android);you will be stunned to notice how pathetically sluggish Samsung is when it comes to upgrading their OS!!!
The Skycure revelation about MITM Attacks on Samsung Default Keyboards is another case in point today-www.skycure.com/blog/skycure-protects-against-the-samsung-swiftkey-vulnerability/
