Well,the latest version of Android has arrived,and while it was exclusive to Google's Nexus 5 for a few months- flagship devices such as the HTC One (M8) ,Galaxy Note 3,Moto X and G are beginning to receive the latest update to 4.4 Kit-Kat. Android L (5.0) will be arriving this fall.
Conclusion: My personal preference right now is: BOTH. I've been a supporter of the Android platform since Google's G1, and since then I have had the luck of owning the Galaxy Nexus, HTC One, Galaxy S3, Nexus 4. (phones) The Kindle Fire HD,Nook HD, Galaxy Tab 7.0,Nexus 7,and the Hisense Sero Pro 7. And while they all were decent little gadgets in their own right,none had the same user experience. Nor did I feel as productive as I could be away from a desktop/laptop as I should have been. Then I had the opportunity to get an iPhone 4S for a low price,and I did. After a little research into the well organized App Store, I was impressed with the amount options from business to graphic design,to music production.Some apps available for iOS is in some ways more advanced than the PC/Mac platforms.But the OS as a whole feels too restrictive,even more than OSX.Hopefully when iOS 8 is released, rumors of Apple merging iOS and OSX functionality are more true than fable. Lately the Google Play Store has been catching up to those apps in the content production dept. While the vast variety of Android devices themselves creates inconsistencies in the user experience, flagships by Sony, Samsung, Motorola, and most notably HTC has begun to match the iPhone in build quality.For most users ANDROID WILL FIT THE BILL. If you find an Android device that you appeal to,you would probably find it more than satisfactory, as Android is just as competent as iOS in CONTENT CONSUMPTION and CONTENT CREATION.
