This may sound very old school but i have just noticed a feature on the n97 that reminds me of my old Nokia 8210 (what a phone when it came out first).
I was just flicking though some of the settings on the n97 and noticed that you can set the default snooze time on your alarm and calendar.
I used to love the 8210 as when a reminder or alarm went off, you could not only select snooze, but you could also select the snooze time there and then... so if you had a reminder to call someone, you could set it to snooze for 1 hour if you liked instead of the default 5 minutes that is common now... why did nokia get rid of this function as they developed new phones.
My last phone (n95) allowed you to click snooze, but that meant that the alarm or reminder would snooze for 5 minutes (no option to change it even in the settings (correct me if i am wrong))
As i said above, i have just noticed that the n97 allows you to set the default snooze time in the settings of both calendar and alarm... hopefully soon we will see the option that the 8210 had, which allows you to set the snooze time when you select snooze there and then...
