Android TabWidget without TabHost - SingleTabWidget

I am a big fun of fragments in Android. Design with fragments is very useful for developers when you think about different ui for phone and tablet. And we have an ActionBar when we want to design our interface with Navigation Tabs.
Before fragments and the action bar, we have used TabActivity, TabHost and TabWidget for tabbed design. Now, we can use the same structure for fragments with FragmentTabHost. Are you sure?
