Re: Comparison of openness
I find it quite hard to believe that your post here has prompted some down votes!
I should be an iOS person - I have 3 Macs in my house (typing this on an rMBP) and I bought my wife an iPhone and an iPad. However, for my phone and tablet requirements, I too find Android a better fit. That's not to denigrate iOS - it does what it does very well, but at this point in time it doesn't do what I *need* it to do as well as Android does.
Your point about data sharing (via intents) is a prime example of this. Another is screens size - I regularly use my Galaxy Note 3 (and the Note 2 and original Note before it) to access servers using remote desktop. The screen size and resolution of the Note range is vast superior than the iPhone's for this particular purpose, and the S-Pen makes an absolutely superb mouse replacement when a finger simple doesn't give the required precision.
The point is that it's all horse for courses. iPhone for works you? Great! WP8? Brilliant! Android? Good for you!
Personally, I welcome the choice.
So, here's an upvote for your trouble.
