I think you're a bit of an edge case, to be honest. Semi-professional camera manufacturer?
As for banking, well I'm clearly very conservative (with a small 'c', let me make clear) when it comes to trusting my details over the web. I have never banked through my PC or phone because although the cryptographic technology to do so safely does exist, it is very brittle. Any mistake in the it's deployed can undermine the whole exercise. The GOTO FAIL bug proves that even Apple can get it wrong and if you're thinking Android, the Stagefright exploit shows how comprehensively Google can mess up and is only the latest example.
It's instructive to see how Google react when a security flaw is made public. When the BBC pointed out that a Tesco Hudl tablet only deleted the directory tree when reset, leaving files readable, Google made a statement that Android users should turn on device encryption before resetting.
What's clear here is that Google regard the onus of personal privacy to be on their users, whereas Apple and Microsoft rightly recognise this is part of their responsibility. Ordinary users simply do not have the knowledge to even recognise a security flaw, leave alone obviate it. When Google do act on security, it is always retroactively, releasing patches which even they know will not be distributed to the majority of affected users. They also don't stick to their own 90 day rule on going public with such exploits, they asked Zimperium for an extension despite denying Microsoft any. (I hope incidentally, you all have the Zimperium Stagefright detector app on your Android devices?)
Security requires competence and commitment, and in my opinion Google have neither.
You see that I don't regard Android as an option and like others here find iOS dull, so it's just fortunate that I like Windows Mobile so much and that it has proved so reliable.
There are limits though, given that I have to factor in the cost of a decent 128GB SD card, I doubt I'd want to go over ?600. Also, I want to see what my options are: Does the Snapdragon 810 cause Cityman to overheat? Is that shiny ring around the camera on Talkman really as ugly as it seems and well, both models lack elan. Is anyone else going to release a WM flagship and what about a Surface phone? That might meet my needs better.
In short, the answer to your question is yes, I will and do so with the hope that Windows 10 will make the app gap smaller and will gain greater penetration than before.
