Google's getting B(l)ing

If I want to look at one of my own pretty pictures, or some other picture I've chosen myself, I'll just make it my desktop background.
One reason is that the customised background makes users feel more accustomed to the concept of a "cloud desktop".
(Except those users don't think they're making a mess of their ability to customize... they think they're expressing themselves, yo).
Interesting. This is actually what first came to my mind: Google is copying the desktop? Not Bing. As many of you said, Bing isn't the first web page to put a pretty background picture (some of the first web pages were the first web pages with pretty background pictures, were they not?). And, as we concluded, the concept is different - choosing, instead of getting a random pic.
So, now you can change the "desktop background" of your google homepage - "the Internet", as often called by many people where I come from. Add some shortcuts to the picture with pretty custom icons (links), support for a clock, a calendar (widgets), a tray or a bar with quick launch and various options...
If only a browser existed that loaded automatically when you start your computer, without the need for all that "windows loading stuff"... :)
I was aiming at the concept of the "cloud desktop", as kierank commented in the meantime.
You could probably change the script a bit to wget Bing's image into /tmp or somewhere and use that.
Basically, I have found very little difference in Google and Bing's search. They are both equally functional and fast. If anything, I've found that I have no reason to switch back to Google - Bing's daily rethemeing adds a little spark to my day.
I encourage everyone to try this for a week. You'll be amazed at how undifferentiated the two major search players truly are at search. These little user delighters are going to be a huge component in the battle for search revenue in the near future.

Also, if the photo is user-configured rather than changing every day, it can be cached.
That said - I may well waste more time changing my background image the way I do my wallpaper.
It took me a couple months of using Bing to figure this out, but if you mouse over the little copyright symbol in the bottom-right of the image, it will tell you who took the picture and what it is of.
So it's good for their stats department.
