Basically, that’s the first thought that came into mind. Most of the features are evolutionary, and long time Android users will scoff at these, having enjoyed better notifications, Twitter integration, and cloud services for the longest time.
iCloud and iTunes Match are interesting, and their use-case and tight integration are something that Android users will long for. Google will have to tinker some code in Android so that Android users can enjoy such tight integration with cloud services. And Google Music Beta just became antiquated as compared to iCloud and iTunes Match. In this case, their first-to-market beta approach bit them in the ass.
Overall, not enough for me to switch to iOS. Well, Apple has to make their devices CHEAPER before I dive into iOS again. Now, for OS X Lion, it’s a different matter.
(iOS 5 is now available as a preview for developers.)
