Nokia didn't abandon anything. Developers are abandoning it!
Just look at how you need to _prod_ developers to NOT remove support for the N8x0 from their apps. Certain person here removed N8x0 support entirely from a certain piece of code that I made "just because he could" (then fortunately added it back when requested). It's hard to convince developers to develop for a platform they don't have!
MeeGo is already on the N8x0 (if MeeGo ever gets a default OSS tablet UI, not twm, we'll see ;P ).
