These applications have earned a permanent place on my N95:
Navicore
Full-featured navigation program. Supports points of interest (including your own) and the N95's internal GPS receiver. See bartmanekul's review of a range of satnav applications in another thread.

Opera
Internet browser. More powerful than the N95's browser, although the two don't coexist very happily.

Mobireader
An e-book reader. Dictionaries, novels and reference works are available in Mobipocket format, and you can use a free PC application to create your own e-books.

DivX Player
Plays avi files encoded with DivX. Good for short clips, but film-length files tend to get out of sync (assuming you don't go blind first).
