It's a lot easier for Nokia to do that because they use a version of Android that's basically stock. Samsung re-skins the UI and adds a bunch of features, so every time they upgrade to a new version of Android, they have to re-apply all those patches. (of course, whether they should do that is another question...)

That's part of the problem and why I rather not buy highly custumized versions of Android.

Given how android has been developing I'm happy to have done features from OEMs that google hasn't added yet.
