HTML5 API - Availability and Features

Question

I just read a little in the File API, and now I'm wondering when almost all major browsers will support it or already support it:

Firefox since version 3.6 Chrome starting from 8.0

? Opera, IE?

Is this supposed to be the successor / alternative to flash-based downloaders, like plupload or sfwupload? What is the advantage and disadvantage of this in this case?

Can it reliably handle Blobs (byte streams) / files so that when reading FileReader input streams, does it have the same consistency as loading the source file from the file system? I mean problems with coding, etc.

After the user sends the file, can I freely use it without any restrictions using javascript? For example, save the file in a variable and then send it via XHR?

I read all this in the specifications, but I would like to hear opinions about who has some experience with it. I'm going to implement a sophisticated user interface, and with the File API it will work much less on the server side ...

But I'm not sure if I should use this or not because of? Opera, IE?

Answer 1

I have no idea when / if IE will support this, but they can be caused by public demand.
