Corresponding to a report by In-Stat, HP is pushing Android into Netbooks. From the Information Alert:
"This solution bypasses the huge memory, storage, and graphics requirements associated with Windows and lowers hardware cost, as well as the software cost. It also addresses the changes in the market. Over the past decade, we've seen two megatrends in electronics – mobility and the Internet. As content and applications migrate to the Internet, these trends will change to mobile Internet and Internet ubiquity. Adopting Android or another open source OS with a custom UI and good browser technology addresses these changes in many specific applications and usage models."
I do agree with the article, and I believe that Android will have a bigger impact on non-smartphone devices (such as Netbooks) than it will have on smartphones.
Symbian is not behind on all this. According to this article, the S60 5th Edition runs on a "off the shelf Intel Atom based motherboard", which means directly on the x86 hardware. The difference is that Symbian runs on x86, while Android runs on ARM.
