>neither rio or acme will work well on a cell phone. i think that's probably true of rio, but while i had an ipaq running inferno, i used acme exclusively and i'm not so sure about the unsuitability of its overall approach. i was using it without modification and although there were undoubtedly things that could change to make that smoother on such a device, i thought it was much less frustrating than my Palm Pilot (old style), in the sense that acme gave an integrated feel whereas Palm had the usual apps approach: `the screen is an address book' (ie, mostly text), `the screen is a diary' (ie, mostly text), `the screen is a notebook' (ie, almost entirely text), and `the screen is a sketchpad' (ie, caught you out there). i could have several things of different type in acme frames--possibly an untyped user interface is more dynamic, compared to the `one at a time' feel of the Palm.
so many user interfaces got stuck in the mould of the Xerox desktop metaphor, and have mouldered there ever since.
