Hard to say really but probably a Nintendo DS when I was quite young. Back then, it was so cool to have a portable gaming system and I loved it for quite a long time. Now, if I get some good pairs of shoes, I would consider that a good present lol. How times change.
I once received a laptop for my birthday, that was the biggest surprise because i wanted a laptop for so long but could afford it. This was back when i was younger, now I'm more giving myself presents instead of receiving them from others
