The fact that they did J2ME multitasking on a feature phone better than Symbian S60 did multitasking of native apps, and did it before the iPhone got any form of multitasking at all always impressed me.
Not to pile on... but let me pile on: symbian seemed eternally bureaucratic, lost in OO abstraction hell and lacked enough demo scene people who knew that a solid 60/72 fps is what mattered.
People from Future Crew (Finland) and Triton (Sweden) should have been running these teams. Half ;-).
