My list of cool apps running well on N900 with Leste:

- SMPlayer (see N900 wiki for settings)

- Audacious (really cool with internet radio)

- Twinkle (SIP calls and messages work perfectly with ippi accounts and probably other SIP providers, /etc/pulse/daemon.conf must be modify to get audio working)

- RetroArch ( NES and SuperNES emulators work fine, see N900 wiki for settings)

- Viewnior (simple image viewer)

- Transmission (works with both torrents and magnet links)

- Thunar File Manager

- E-mail (the Maemo stock app, compatible with imap4)

- HamsterFiler (fast file browser with keyboard, a bit slow with touch screen)

- NOMWeather (really cool)

- Yt-dlp (for download and stream from many web sites)

- Links2 (the best web browser at the moment, working well in GUI mode with Hildon composition disabled : Ctl + Shift + N, but lack of javascript)

- Irssi ( for IRC of course but combined with a local Bitlbee server it is possible to use FB messenger, Signal, Twitter and others...)
