While many of these maybe available for download, they don't integrate into the OS and aren't used to open default file.... then need to be.
- Full Featured eReader - one that allows text books to be studied - multiple color highlights and easy book marks, and can open most of the major formats. I like BookReader for the PlayBook, but it very limited in features.
- Photo Editing
- Video Editing
- Video Player that supports a wider range of formats
- Mapping / Directions / Compass
- Social Networking - They all need to be available, my wife is into Pinterest these day - it isn't on the PlayBook, tried the Android version and it doesn't work right.
- Cloud Storage - one place to access the BlackBerry Cloud (there needs to be one) along with 3rd party Clouds like Drop Box, Google Drive....
- Health & Fitness - Track your Pulse, caloric intake, medicine reminders...
- Office Suite - one that works - Docs to Go for the PlayBook is NOT a professional grade Office Suite.
- File Manager - one that works - Files & Folders is great for the PlayBook, but it should be a default app.
- Child Lock - need to be able to open a game or a movie on my BB10 device and lock it so that a child can not access anything other than the opened application.
- Remote Desktop - Would be a great feature for a device that is geared towards professionals.
