While a quick search failed to turn up the post, I recall that some time ago someone posted a suggestion that future tablets should contain a switch in the stylus silo. With the stylus is stored, the tablet works in its default, "fat finger" mode, but then shifts appropriately when the stylus comes out to play. This automatic transition would be in line with other magical, magnetical tricks the tablets perform.

Of course, there are downsides. This magic would only work on those theoretical future tablets that contain the switch. Applications would need to be coded specifically for the platform, with UIs for both modes. Unlikely, while we're still starved enough for software that we're often happy to get rough, un-Hildonized ports. And losing a stylus would cause even more frustration than it does now.
