Should developers use Flash or HTML 5? User interface expert Anthony Franco says it depends on what you’re building. For applications that won’t be accessed by mobile users, he recommends Flash, but for those who will, he says to use HTML 5.
He says the ongoing battle “is not helpful for developers.” And he adds that they have two choices: “They can either build [the application] twice, or build it less.” He believes that so far most developers are choosing to build apps twice, so that they provide desktop users the richer experience of Flash, while still making their apps accessible to mobile users.
