The Trouble with Twins

They've come a long way since their first Christmas in 1999!
Buying gifts for the boys is always a little bit tricky. They usually want the same thing, but I can't imagine it's a lot of fun to open a gift right after your brother and know what it is because you always get the same thing. So, the question is, do you get them different things so they can be surprised when they open them, but risk one being disappointed because he didn't get what his brother got? Or do you get them two of the same thing so it's "fair", but have the excitement taken out of seeing what is inside of your package? Or, do you get them one larger item together, which really seems unfair to have to open a gift TOGETHER, but has the added benefit of being able to get more expensive gifts. (Said benefit lost on six year olds with no comprehension of what things cost.) From older twins that I've questioned on this topic, the consensus is usually that they prefer getting different gifts. I'm hoping that as they get older and develop more diverse interests apart from each other, their lists will look completely different and this dilemma will be solved. But for now, here is their list:
Playstation and games
Air hockey table
Heely's (What are those you ask? Shoes with wheels of course!) Size 13
Scooters
Black Spud Hockey sweatshirts
Turbo sleds
Drum Set (please no)
Watches
Sleeping bags
