Not wishing to offend, yet support folks to move into Diablo, yes it is working "out-of-the-box" great, you just have to work at it if you want non-OS installed applications to work. If that does not seem like your
'cup-of-tea" you are warned. I find listing what does not work very unproductive due to others saying it did and other saying it did not. So in hopes to move folks into a positive viewpoint I am listing what is working, for me on my N810 and my daughter's N800.

WARNING !!! All total about 5 hours of effort (not counting the flashing) with Ermining, GPE Summary, GPE-Calendar and OMWeather being the ones that took work and waiting until fixes were posted. Otherwise easy install and the automatic updating (OTA) was so very cool to get a notice to update, while the message could be clearer, not a big deal as you just say yes and it worked without a problem for me. Here is my list:

1 Standard Install items (all that comes with OS)
2 load-applet
3 Canola
4 Countdown
5 Ermining (GPE to Google cal and back)
6 GPE Summary
7 GPE-Calendar
8 Maemo Mapper
9 Maemodrac- solitary
10 Map
11 Midnight Commander
12 Mplayer
13 OMWeather
14 openssh
15 Personal Menu
16 Putty
17 Skype
18 WinSCP

Yes a few items took a little work with help from folks here and researching - so much for being on the "bleeding edge" as one seems to have to bleed some blood (blood=time/effort/happyness) in order to be on the "1st to own it on my block" kind of thing.......
=====================
Small suggestion, when posting what does not work, a posting with one specific program/application would sure help as when I open a post they seem to start with one that does not work and then go into different ones that do not work and/or what does work...to much effort for new folks and (for sure I find it so) a little overwhelming and confusions sometimes...just a suggestion....

This is a great list!

I have a few more working under Diablo:
19 leafpad (an editor)
20 Quiver (viewing photos)
21 evince (pdf viewer)
22 python
23 PyPacker (a Deb packaging tool)
24 bash (a more intellegent shell <http://www.makikiweb.com/n800/downloads/bash_alone-3.1.17.armel.deb>
25 expect (a tcl like programming language)
