So...tell me: why do people like digital cameras?
My sister borrows my camera to take pictures of her her daughter, my nephew, and my lil bro. Kids grow so fast that it's a good idea to take pictures often.
Would regular pictures work? No, our paper pictures are in some container, although the right thing to do is to keep it in an album. Even if they were in an album, they are not as accessible as having them right in your computer.
Do you have any relatives living at a good distance from you? Let your mom know you can share pictures with them by email... free. You can even create a homepage to display your pictures, using the webspace that your ISP allots you. Also free.
Going back to the being a kid point, I'm 24 years old. In the days when I was a lil kid, I think it was a luxury in my town to have a Polaroid instantaneous camera. My father had one and with it he was able to take pictures of my siblings and I. Looking at them, I realize that I wasn't always such an ugly mothaflowa... hehe. It's great to see old pictures of the whole family, actually.
With a regular camera you're more careful as to what moment is worth a picture because each one will cost you dinero ($$). With a digital camera, take some pictures, upload them to the computer, take more pictures, upload them, too, and then decide which ones you'll keep, if not all.
Oh, and just so you know, I paid $379 bucks for my camera. In the first week or two, I think I regretted having spent so much. With time passing, I got over it. Now, I know I made the right choice.
You can get a decent camera (1.3 megapixels) for about $100 bucks. Get one with a timer in case you ever want to strike a pose for your AOL guuuuurrffffriend...
