Buy it?

I have a decent digital camera but you know what? I take pictures to post on my blog, to send to friends and family and to keep as records. I don't print them, I don't do anything too terribly complicated with editing them. I use picnik.com to quickly edit and then save either to my picasa site or my hard drive. I'm not terribly organized about my pictures either. So - I am thinking of buying a second camera, small and tiny and cheap to take with me on my walks and in my car. I've seen them for as cheap as $20. I could take pictures of the cats of Moberly. I saw four on the way to work the other day and it just saddens me that I am not prepared to snap. So stand by, while I figure this out - the deer I saw on my walk in the park today, the praying mantis on the building downtown and the cats of Moberly might be arriving in lovely low definition color!
