Another feature to organize life!!

Think of this: You're on a business trip visiting multiple places and your last leg of your trip you'll cover by train via New York City, with an hour's wait time. Your wife's tasked you with picking up something important while you're in NYC.
While on your trip, you're completely tied up with calls, resolving issues. You realize that you need to set a reminder so that you don't forget to pick up your item. So, you pick up your cell phone and you set a reminder for 2:00 pm on 23rd of June 2010, because that's when your train arrive at New York city.
On the day of your train journey, you're even more busy with calls. And because one of your appointments got cancelled, you boarder a train one hour earlier. Now, you can board your train back home from Grand Central at 1:00 pm instead of 3:00 pm. In the middle of all these, you completely forgot about the item you need to pick up. You reached there early, say at 12:00 pm. Your reminder doesn't kick off as it's too early. And as you've been so much caught up in other tasks, you completely forget about this one task which you can accomplish only while you're in the New York City. Two hours later, at 2:00 pm, while you're riding your train back home, your reminder blows off and you're made aware of the fact that you haven't done this one thing on which you've to provide a status to your boss (wifey) when you reach home. You think, "Ghoss... why am i such a mess?"
But wait a minute, what if you think a bit deeper, as if you're preparing a root cause analysis report. Now you'll ask another question: why can't I set up a reminder by location instead of time? Why not? Your phone can locate you to where you're, at least to a couple of feet's precision. Well, this is yet another feature which can be provided by the cell phone (could be another app on iPhone) to make our life a little bit more organized, a little bit more easier: Ability to set reminders by location!!
BTW it's totally a different discussion on whether these additional features have made our life easier or more complicated!
