I only have regrets in terms of buying game systems.
The Wii played it round my mates, thought "this is fucking amazong i have to have one" i had fun on Wii Sports and Red Steel though Red Steel made me tired, and when i got my new HD tv at the time it just looked rubbish compared to my Xbox 36 & PS3.
The second was my PS VITA, sure i loved Persona 4 the golden and Uncharted & Gravity Rush were good Triple A's, but i need more than just aload of indies.
So do u regret buying a games system?
