Nokia has to focus on what they know, and that is phones. With phones comes Symbian^3/4. Nokia is developing MeeGo for ARM, but why exactly, when Intel based Meego will outperform anything that Nokia will put together using ARM CPU's ? The only reason I can think of is to make MeeGo as widespread as possible (vs Android/MS), but why do it at the expense of Symbian?

After all, Symbian was used on "mobile computers" long before the term was invented.

Anyway, more Meego devices from other vendors can only be good for Nokia.
