I use Windows on my desktop for convenience, but I'd put as much trust in Windows on mobile as I would running it on my servers; which is "not at all". Microsoft just isn't good at security; never has been, never will be.
Android and IOS are already pretty crap at security, with much more important data than you generally get on a desktop, can you imagine how bad Microsoft will get it?
I'll stick with Android thanks, no offense to your purchase.
