dont know if I would recommend LauncherPro for a no tech type
Advanced Task Killer - Active but unused apps drain your battery power, this one kills ones your not using.
Angry Birds - Free game, fantastic time killer. If you dont try it, you are going to end badly
Astro File Manager - Manages files, oddly enough
CamCard - Uses camera and OCR (optical character recognition) to scan businees cards and add them automatically to your contacts
Cardio Trainer - tracks workouts, biking, walking/running/rowing, kayaking by duration and speed, saves workouts and maps of same using googlemaps.
Droidlight - turns on the LED camera flash for a decent little falshlight
Google Search Widget - Keeps a search bar for Google, and its voice search funtion, resident on your desktop.
LookOut - Backs up your phones data, scans downloads for viruses, and allows you to track your phones current GPS location via any comuter. Guy in NJ got carjacked, used Lokout to tell police where his car was, they got the car in seven minutes. Also lets you remotely wipe the data on the phone in case it ends up in the wrong hands.
Photobucket - Upload right from phone to PB, nice and simple.
Tip Calaulator - allows fast multiperson tip calcs.
UPS mobile - nice in the holiday season
Banking apps - depnds on your bank, but very nice if the do.
Zillow - Great real estate app, can show you on the map where houses are, and one touch nav to that house.
