I wouldn't use any Android device because of security worries, but I do own a (apol) Sony WalkPerson that is Android based, a really old os, and because this device isn't connected to the Internet then I have no worries about security. Don't think that counts as enough of a level of experience in Android or Sony products in general. The Sony in-house malware CD scandal is enough to out me off buying Sony anything, same as the Phorm scandal means I will never buy BT.
I am a big Microsoft fan, but Windows 8 put me off using the products and I haven't done so in several years. I would rather like to know a bit more about Linux or BSD. iPad is what I use on a daily basis now, even though its crippled nature makes me frustrated. The fact that iPad apps can be uninstalled is a huge selling point in favour of iOS to me. I love my Blackberry Z10 (QNX) but don't use it much any more because I don't go out, unless I am in hospital, where the BBZ10 gets used as a 3G modem, needs updating to LTE poss.
Apol for wildly off-topic nature of this state-of-the-Union post.
