How many photos fit on a 4GB memory card in a 10-megapixel digital camera versus 4 megapixel?

On a 10 megapixel sensor you will probably be able to fit over twice the amount of photos that you will take with a 4 megapixel sensor. I guess 4,000 Photos compared to 2,000. There is always a BUT, 2,000 to 4,000 photos is not worth loosing so much resolution. You are still talking about thousands and I'm not sure if you will even be able to take 2,000 photos in 4 or 6 months. I'll say take the 10 Megapixel camera with the 4 GB Card.
