It was inevitable as Android advanced to an equal in elegance, features and open file formats.
I have a Google (Nexus) 7” tablet that is every bit the equal (and I think superior) to the iPad.
The Windows 8 phones and Surface are also really cool. I have a Win 8 phone and program for Surface and Windows 8 desktop at work.
It is really great that all the environments are so similar and apps can be easily set up for all the platforms. MS had slipped in recent years, but they are a serious threat to regain or stabilize their ground with this product.
I love my Windows 8 phone.
I have both an iPad Mini and a Google Nexus 7". I agree with your statement. It took me about 5 minutes to "figure out" my iPad when I received the iPad 1 three years ago as a gift. The "Mini" was an upgrade/gift from my family. As luck would have it, I now also have a Google Nexus 7 which was also a gift. That took me about 15 minutes to figure out (mostly due to differences in "app stores") and I have to say I like the Nexus 7" about as much as my iPad Mini. I still think the iPad Mini's easier to use, but I really am liking the ability to customize the Nexus' OS interface (Android Jellybean) better.
I'd also compared iPhone 5 to Samsung Galaxy II and when it's time for me to upgrade phones, Galaxy II it'll be. (That coming from a loyal iPad/iOS user.)
I suspect I'm not going to be alone.
New Samsung Galaxy sells for the same as iPhone 5 so that must tell you something. That it is equally coveted. Check out the prices for raw phones (no plans) on ebay and you can see this
Instead of focusing on new features, what they need to focus on is how to get better battery life.
