Then you didn't explore the capabilities. I refuse to use an non-jailbroken device. That's actually why my old iPod was still running iOS4.1. I didn't update to 4.3.3 until I knew there was an untethered jailbreak available.
I can use SSH, VNC, terminal, and more on my device. It can also run Python. I can login and transfer files to it remotely then retrieve them later. Jailbreaking turns the device into essentially a linux machine in your palm.
