Ralf Rottmann is CTO and co-founder of the largest mobile application developer in Germany, Grandcentrix. He has more Apple devices than an Apple Store and thinks he’s a fanboy – yet, he’s switched to the Nexus 4 completely, stating that “the latest version of Android outshines the latest version of iOS in almost every single aspect”. This line in particular rings true for me as a Windows Phone 8 and Android user: “whenever I grab my iPhone for testing purposes, iOS feels pretty old, outdated and less user friendly”. This will most likely be dismissed as a troll by some, but it has to be said: iOS has become stale, bordering on being outdated, and lacks several crucial pieces of functionality, neatly detailed in Rottman’s article. Apple has a lot of catching up to do, or it will be Mac OS all over again.
