Until a year or two ago there was a stalemate as far as "rich web" development technologies goes. Neither flash, Silverlight or HTML5 was the clear winner. I remember people being incredulous that the iPad didn't support Flash, saying that while it might be ok for the iPhone to not support it, nobody would take the iPad seriously if it didn't support Flash. In a way, I think it might be the combined weight of the iPh…
That sounds like revisionist history to me. Plenty of people complained about the lack of Flash and speculated that Apple might eventually have to give in and allow it, but I don't think any significant number of people suggested or believed that the iPad wouldn't be taken seriously without it.
