An interesting development in the Apple front: they published today the key features of upcoming iPhone OS 4: multitasking (more power to the user), iAd system for monetization (more money to the developer), and Game Center (friend invites – here we go, Facebook apps). Nice to see how this will work out. – Oh yes, and our Apple iPad should arrive from the States tomorrow (thanks, Lori!), so going to the extended touch screen experience will also be interesting. The version 4 OS will not be arriving to iPad sooner than next autumn, but I will be installing one to my iPhone 3GS in the summer, though.
