For some webapps YES, but seriously using HTML5 is broken in many ways. As soon as a server is down the app is non functional.

also the fact that HTTP is mostly done as a one way communication protocol makes it less good in many ways. Also it makes we wonder why on earth people needs triple core CPU:s smartphones if 'everything is about HTML5 this days' why do we need that when HTML5 will make apps dogslow cause the app constanly have to request data from the cloud?

No, seriously HTML5 may work in many ways but there are alot places it will not work.

Thats why I say its overhyped. But developers are lazy this days and dont want to learn more low/midlevel programing languages and thinks HTML5 is soooo good for everything.

Not even in university in sweden they learn anything less than Android SDK and HTML5 but nothing about lowlevel embedded Start make me wonder why the hell people bother to ask why europe going down when the answer is obvious....
