So, what's the reason, Google? My guess is that with Google's Chrome OS on the verge of release, the great Google geniuses are giving us a taste of what it might feel like. Without Microsoft, without a desktop, without all those PC (and Mac!) familiarities, Google has to bridge the gap.
Step one seems to be to introduce the "wallpaper" to Google -- thereby transforming your Google homepage into a desktop (or into a desktop-like experience!).
Now, you can customize your Google experience, just like you can currently customize your PC or Mac experience, but, of course, without all the burdens that come with bloated operating systems, such as applications and features you don't even need. This will most certainly be Google's future pitch for its shiny, new OS!
Does Google's new homepage enhance your experience or is it just another web-based distraction? It is smart, though, I will contend. As almost everything from Google is. Even when we doubt Google's zany new offerings in the beginning, as we did with Gmail and are now doing with Buzz, Google has consistently outwitted our skepticism. The geniuses are testing the waters, sharks abound. For me, I have a take-it-or-leave-it attitude for the wallpaper, but, for the masses, I predict it will grow to be a fan-favourite!
