What is QuantumStep? The hashtag doesn't seem to have had a lot of use, and at least half of the tweets seem to relate to clubbing. Searching the internet for QuantumStep just dumps me at the GoldenDeli homepage, and I can't find anything about QuantumSTEP on there.
Ah okay, cool. Sounds like myStep is the GUI toolkit and QuantumSTEP adds address, phonebook, calendar apps presumably targeted at devices like the OpenMoko making them a phone as well as a linux kernel and windowing system running on a handheld device.
