I got my N900 about a month ago and I've really enjoyed it. I have been reading these boards to get ideas for applications/widgets to make it even better, but I must admit I'm having trouble following some of the more technical descriptions of applications and other downloads. So I was wondering if people could tell me what I am really missing out on, in a way that a non-tech person can understand.

Right now, the main widgets I have used are: RSS (the one the phone comes with); the bluetooth switching one; the one that displays your text messages on the from screen; and the search/google one.

I use the default browser (Rather than downloading firefox or chrome, even though I use chrome on my actual laptop)

for applications, I use: hermes; xjournal; angry birds (although I've beaten that recently and need a new game); I haven't really used the GPS or easy park features because I haven't really traveled much since I got the N900.

For emails, I use the nokia email thing, although I have to go to the gmail website if I want to search my old messages.

So... what am I really missing out on?

FBReader for eBooks is nice.

GPodder (along with Panucci) for podcast downloading and playback.

An emulator if you like games like DrNokSnes and PicoDrive so you can play all the old SNES and Megadrive games.

download swf flash files and play any flash content offline
fill it to the brim with movies music shows (add a 16gb micro sd card)
undervolt to to get more battery life
overclock it to make it faster
get the manual focus +flashlight app to make video recording awesome
tweak it with themes and wicked wallpapers from the n900 wallpaper site

etc
