Cloth diapers are not what they used to be, although there's a lot of people who still enjoy using the flat ones with pins. They now come with velcro, snaps and are as easy to use as disposables. They are easy to clean and MUCH better for your child.
Here are the facts about the disposables vs. cloth:
Disposables contain Dioxin, which has been shown to cause cancer...do you really want that next to your childs most sensitive parts?
They fill up landfills 5,000 and 8,000 diapers per child, depending on when they are potty trained. You are supposed to "shake" the fecal matter out of them and flush it down the toilet, JUST like cloth diapers.
Viruses (such as polio and yes, it is excreted in the fecal matter when you get your child vaccinated as are all other vaccinations) can live in landfills and contaminate our soil & water supplies for many years. At least with cloth, you wash it and kill any virus so it doesn't spread.
Here is a web site that explains just how dangerous disposable diapers are for your baby
