Oh god no. Thats how it works on S60Browser. It seems it is assumed that I want to run a web browser, use the bookmarks, and then see my feeds. No. Backwards. I first check RSS and then decide to open the browser. I want my RSS feeds like e-mail (IMAP). Quickly wade through the subject lines. Perhaps click a few. And then maybe save a one, maybe send it to my e-mail for later, or maybe open it in a browser -- if the situations allow it. I can only speak for myself but I assume people want to be able check the news in a glance. If you wanted to check in the way you describe, might as well simply surf to the sites instead of using RSS.

Also, while RSS is distributed over HTTP usually but because its a defined standard the content can be parsed and used for other purposes. Much like a shell or a shell script. Doing this with HTML and JS is possible but is inefficient because 1) requires to download more data 2) bloat / requires heavier application 3) contains noise (banners etc) and potential UI inconsistensies. One can argue the parsing won't be used much on a tablet. Could very well be true. The other arguments still stand though.

Perhaps its better to allow the RSS feeder to be embedded in the browser, but also allow it to run seperate. I saw a demo of Java FX and Google Gears with such function. Very interesting.
