I think I have an explaination on why technology doesn't well with Wizards. As we know technology needs constant and specific energy in order to operate. Wizards emotions cause energy to shift and change. So when an wizard goes through life he or she continually shift thoughts and emotions causing tech failure. Presumably a magical surge protector stabilizing the energies in the area (specific to electricity) would address the issue but impeding any electrical spells. Just a thought.
Let me know if you think that makes sense.
