iPhone Or Not

Some friends are fantasizing about getting the iPhone 4. On the other hand, I am fantasizing about getting the Canon telephoto lens or as a start the Canon Speedlite external flash. A year ago, I would've fantasized the same with my friends but after acquiring the Canon EOS 550D last year, my interest shifted. I learned that photography is a never ending learning experience. Upgrading the lens seems much more attractive than buying iPhone for now.
