Oh, I forgot. Saner handling of concurrent sound sources is needed. If I'm getting voice guidance from Sygic, I still want to hear them when I'm talking on the phone, or listening to music, etc. I don't really know how best this should be handled, but some way to prioritise, attenuate or mute sound sources with dbus (or whatever) might be something to consider. If the device is to replace my netbook, TomTom, iPod and phone, it needs to let me use all those functions concurrently and sanely, without compromise. Especially when driving.
