Neat app, I suppose. Just not worth the money. I mean, how hard is it really, to change your desktop backgrounds manually? I suppose if you like to change your backgrounds a lot, it may be worth it to some...

As far as downloading wallpapers for you... it only does so from one website (correct me if I'm wrong). If the n900walpapers.com (or whatever that website is) had thousands of wallpapers, I could understand, I suppose. But even that site doesn't have a lot compared to what our good friend google shows us when we google 800x480 wallpapers.
