iphone

few months ago my colleague was looking for a new pda to replace his ageing o2xdaii mini. i had the same brand also. now i am using i780. since his budget was below 2k so i suggested either e71 or i780. so finally he bought the i780. soon after that out was iphone. then i saw that he bought the iphone. i still prefer my i780 than the iphone. last week i saw he brought back his o2xdaii. why? he likes the calendar of winmo. he misses his gps at i780 as iphone does not provide turn by turn.
see those are some of the reason why i don't switch to iphone and still loving my i780 very much.
