This is where I'm at so far.
I'm continually moving things around though lol.
Far left screen - Blank. Haven't needed it...yet!
2nd from left - Pandora, Cubed music player, and my icons for the camera, video camera, picasa, and the gallery.
3rd from left - tools, misc. internet stuff, battery widgets (trying to decide between the two), the "power strip".
left dock - Google Maps, swipe for navigation. E-Mail, swipe for GMail. Dropbox. Calculator. Youtube.
Center/Main screen - Time/Weather. Leaving the rest blank for now.
Center dock - Dialer. Contacts. App Drawer. Handscent. DolphinHD.
Right screen - Jorte Calendar widgets/Tasks.
Right Dock - Foursquare. AIM. Twitter. Facebook (launches to touch site. The app sucks). Android Market, swipe to AppBrain.
2nd right screen - Weather Channel. Smooth Calendar (probably going to dump, as I'm liking Jorte better). Sports Tap and ESPN. Will probably continue to use both until Hockey season, then see which is better. Then my "Sports" area. The Hockey News app, NJ Devils app. NFL Mobile, and ESPN.
Far right screen - Emulators. (SCUMMVM, NES, GEN, SNES). Then misc. games. And finally my comics/books area. (Android Comic Viewer, Aldiko, Comic Shopper, and My Collection Pro.
I'm still constantly playing around and moving things, adding things, removing things. This will probably always be a work in progress lol.
