well, no. At least not exactly. When iPhone came out I had P990 and it was much better device in almost every aspect. The only thing that was far superior on iPhone was browser, partly because of better and bigger display but most because it didn't rearange the page layout like P990 did. After a few weeks I switched back to P990.
Each new platform is missing something that is crucial for someone but at the same time is full of things that are completely irrelevant to someone elese.
