What takes the place on an iOpener?

Anyway, while investigating various options (Apple Macintosh, Knoppix Linux/Ubuntu Linux with USB key file storage, WebTV) none are very appealing for various reasons. What, o fellow Slashdoter's are the real options today? The criterion are: Dial-up support, no update/anti-virus/etc pop-ups, and no software "update" downloads, support for PDFs, Flash, Javascript, etc. to accomodate modern websites. The i-Opener was 'foolproof", if things went wrong, you could just shut it off and try again, everything I see today lacks that ability (to varying extents)."
