It's not that I'm not willing to share, the fact that it is mobile means it moves with us. Meaning I could be at my grandparents with the GameBoy, and consequently, my brother and sister wouldn't be able to use it because they were, for example, sleeping over at a friends house... We might have been spoiled, but we each got one mobile gaming device of our choosing.
I guess it just seems weird to me.
I share my 3DS with my brother-in-law and my sister all the time. Then again, they can't afford one.
I really couldn't either, but I manage money poorly and NEEDED IT!!
