The new BASIC

I'm seeing many posts that worry about computing devices like iPhones and the new iPad preventing people from having direct control over the hardware. Mark is telling us about a Ctrl+Reset and a BASIC prompt. Nowadays you get started with the following on an HTML page:

    <script type="text/javascript">
    document.write("Hello, World!");
    </script>

And you can do anything! Don't tell me the days of tinkering are over.
