iPad or no iPad...iPad

I am technology enthusiast. Most recently I struggled with the idea of wanting to purchase an iPad. I know I don't need it, but it was hard to satisfy the enthusiast in me. In the end I gave up and bought one.

I hated the feeling of having to make a trade off and struggled with the idea of what a sustainable choice would have been in this case. In hindsight, I will donate a laptop and other items to charity and buy carbon offset from terrapass. Does doing all this justify my purchasing behavior?
