Given this is the longest running topic on the internet, I will keep my two cents very short. Every time I set up a calendar slot or an alarm on an Apple product, I find it just that bit easier – for the simple reason that Apple offers me only multiples of 5 (for setting minutes) which makes the whole thing much faster. So I can set up an alert for 9.15am or 9.20 am but nor for 9.17 am or 9.21 am. Think about this – how many of us really need to have alarms set up for 9.17 or 9.21?
Having said that, I have also realised how difficult it is to truly listen to users & ignore conventional wisdom – which seems to always be on the side of more bells & whistles.
