My daughter (almost 13, diagnosed in May 2009), switched from the pump to injections (with pens) also. She didn't like being attached either. Her BG is a lot more difficult to control, as she doesn't finger stick and bolus as much as she should (sometimes not at all) when she is out being social. It is so frustrating and I worry about her future so much. I could go on and on, but I guess I had better start my own thread for that!
She's been on injections for almost a year, and is finally doing much better at taking care of herself when away from home. Under no circumstances will she consider going back on pump therapy! Recently, she switched to a new doctor at a new facility and we learned of a new pump option.
The Omnipod.
http://www.myomnipod.com Look it up if you haven't considered it. Our family was so excited for this tubeless, nearly painless option. They send out a non-working pod for free to test out how it feels/looks. Unfortunately, for my petite, tight-clothes-wearing daughter, it was still too obtrusive. So, for now, she is still "calling the SHOTS" too.

Maybe your son would like it though... Also, a smaller pod has been developed, but it still has to go through the whole FDA approval process.
