Sadly, this article is extremely useful and relevant. I remember loads of toys I was overjoyed to receive but never played with because I couldn't afford to, such as a neat battery powered remote control race car or a educational learn how to type toy laptop. Most unfortunately, I grew up with computers and have long since held the ability to type faster than thirty words a minute without looking at the keyboard and maneuver around PC's better than most adults. Additionally, that race car was the subject of the next three years of Christmas lists because I really did want to play with it, but couldn't afford the special batteries that went into it. According to the mentality of parents, they look at the gift list and think, "He doesn't really want rechargeable batteries, he's just thinks it's neat", so they never bought it for me. After three years I gave up on it. Seven years later, I'm an adult with a job and and a never used race car in my closet. I could buy the battery now, but it just doesn't interest me anymore and is hardly age appropriate.
