iPod Touch: It got me through my months-long illness and recovery, and I adore it. I have a little rubber case for it and I've done Rushniki embroidery along the back to make it into a Ukepod. I keep it stashed in the car to play music rather than have stacks of CDs.
iPhone: It's my electronic work leash, bed-reader and method of data capture.
iPad: Assigned to me for work. I mainly just use it to take inventory, quickly send files zipping through the ether around the office and take pictures of intricately-drawn and planned whiteboards to send to the people who phone into meetings where these drawings are created.
I like my devices.
