1. The office apps that are built-in. Has anyone used them extensively? I got this for a work phone and will frequently use it for Excel and Powerpoint presentations. I don't mind paying for QuickOffice or the other one, I can probably expense it. Does anyone have any experience with them?

2. There's three apps that seem to be GPS-related. Position, Navigator, and Landmarks. WTF is the use of them? I didn't see any of them working like a GPS tool. I'm going to install TomTom on it anyways, but I'd like to see what these do anyway?
