I might, but again, one of the things I do the most is download tons of stuff from dodgy sources (I do this soooo much on my iphone) and I can't think of anyway id be able to do that on a full windows tablet. If it wasn't for that id probably buy it.
If you deal with dodgy sources, you need an OS that gives you full control. Then you can install browser plugins that inspect the page for potential dodgy stuff like tracking cookies, etc. You can view page source, if you want. You can control firewall, close ports that can be used to exploit your device, and so on. And all that spells Windows 8.1, full version (not RT). I didn't look, but maybe, Android allows some of that control, too, but Windows - no question.
With iOS? You don't know what's going on under the hood when you're visiting dodgy places. You're simply singing a comforting lullaby to yourself that everything is gonna be alright. Think about it: by visiting a certain site, you can jailbreak your iPhone. Essentially, that site completely knocks out the security of iOS. So you can continue to convince yourself that iOS is 100% bulletproof, but you'd be amazed if you actually saw what these dodgy sites can do under the hood.
