You wil always get some smart arse replies on this forum but for the moment I would avoid installing nitroid until you are more familiar with x terminal. Skype should be installed already, as for paltalk, I don't know. Is the an app for web os? That might work with preenv. Gtalk is installed aswell. You definitely didn't get the wrong phone bt the way. I have no idea about linux but have managed to follow some tutorials and some worked and some didn't. Good luck with your new toy.
