i would guess majority of the people probably do use applications from devel and testing and still have less problems than people who are on other platforms. The funny thing is that we can't really relate overclocking and applications in testing/devel to the "stable" topic that i have created because they are known to be unstable :P. My bet is if we took any number of users of the n900 with only stable applications and no overclocking and compare them to any other phone n900 would whip every other phone in running without crashing
