A if for Application.
S is for (web) service.
SA is a combine service and application.
- Google Mobile App (SA): Mail, Docs, Reader, Picasa. The iPhone was the final nail for bloglines -- they don't have an acceptable mobile interface.
- Evernote (SA)
- Epocrates Rx (SA)
- Light (A)
- NYTimes (SA)
- Pandora (SA): this is genuinely amazing; it's going to sell a lot of used CDs. Recommend setting up by PC/Mac first.
- Remote (iTunes/AirTunes) (A)
- Book reader (A) - currently, an old favorite. The Prince.
- Voice Record (A)
(this may be superseded by Evernote's audio notes, but it works without a net connection)
