Well, in 770 the amount of space available is much smaller so the buttons will need to be smaller too. This make hitting them harder, specially with a blunt object like your thumb... I think you are right that 770 will probably be easier to hold like that though. > Fitts' law has to do with distance and efficiency (see the URL posted > earlier).

New keyboard layouts have a phenomenal rate of failing to spark interest. It's not because lack of effort we are still (mostly) using a layout that was designed to slow the writers down (in order to avoid mechanical jams). Even just cutting the layout in half and making it more ergonomic seems to have failed, you hardly see new keyboard models with split keys. Which is a shame. The grid layout is not in violation of Fitts' law (as you seem to suggest), and is probably still faster to use with the stylus than a spread layout due to smaller distances. > > Also the keyboard is most likely useless the moment you put it into > > a stand or on the table... > > I think that's subjective.

Sure, from http://maemo.org/maemowiki/ApplicationCatalog#head-41163224718d3d8a229199825e359d4129ed5c77 I see python (which is very usable although slow to start) and few others, but basically it's just a matter of getting the sources and compiling ;) It's probably not quite that straightforward with bindings though, at least non-gtk. There's always http://www.gtk.org/bindings.html if someone is looking to port new languages (would be greate to get more options for developers!). It's one of the things people like about Gtk+, it's not just C, it's also [insert your favourite binding language here]. Btw, the status page probably lies on some of the bindings (or at least it looks a bit worse than it should be...). -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi
