Pebble watches are already decent. Now you can get Pandora from the Pebble appstore. Pandora for Pebble adds music discovery and control to your smartwatch. Here is what the app does:
Pandora’s watchapp gives your Pebble watch the power to view and change stations; see track info; thumb songs up or down; and skip, pause, or resume tracks.
Pandora for Pebble is available to iOS users. Android integration is coming soon though.
