This weekend as I got to the point farthest from my house on my run, I felt a sharp pain in my right knee. I tried to run through it but the pain continued. So I started walking.
As I walked home, I thought of the Caribou Coffee shop just up the street. I could stop and get a coffee since I had to walk anyway. But I didn't have any money with me. All I had was my iPhone, which serves as an iPod while I run, tucked safely into my water bottle belt.
Then I wondered about Apps. Did Caribou Coffee have an app that I could download, load up with money from my bank account and use to buy coffee? I searched apps but couldn't find one. Then I found the Starbucks app.

During that rather long walk home with the painful knee, I concentrated on adding the app to my phone. I downloaded it and saw that I needed to enter my username and password, which I already had since I'd registered my Starbucks card before. Next, I added some money to the card, and, Voila! I could use my phone to buy coffee at Starbucks. Unfortunately, the Starbucks was not on my walk home, so I would have to wait before trying it.

When I left later that morning to drive to Trader Joe's, I drove through Starbucks and handed over my own cup to fill with coffe and my iPhone as payment.
I'm not sure why it is so exciting to hand over my phone to pay for my coffee. I guess it's just one less thing I have to remember when I leave the house in the morning.
I love technology.
