Still using mine. In fact, I'm just about to reflash and have a play about with the community Diablo project.

I became disenchanted with the whole NIT thing when Nokia abandoned the N8xx products by the end of 2008, but still use it for the occasional road trip and such. I still like to check out new programs and see if there are any new developments (which there haven't been many over the last year).

Still it's a cracking piece of kit let down by Nokia's complete lack of support for the development community, and the prevailing 3g networks over free wifi.

Still just due to money, and the fact that there really isn't anything out there that offers what the N810 does, I'll be sticking with my swiss army knife of portable tablet computers for a while.

Shameless plug...I have mine up for sale in the FS forum for $120 with 8GB SDHC, original soft case, stylus + 2 chargers in very good to excellent condition.

I will say when I picked it up and started playing with it to take photos I was having 2nd, 3rd, and 4th thoughts. It makes a great remote wireless keyboard/mouse combo via BlueMaemo which became my N810's primary use over the past 6 months since getting my N900. If no one buys it I will still not be sad to keep it around.

I still use mine every day, all the time... but I'm a bit of a geek.

I use Quick-Clip mostly... I've written some Perl scripts that make it function as a journal. The scripts let me back it up a couple of times per month while transferring over my "action items" (Dave Allen's version of a Todo list). Other scripts allow me to search both the current journal and all the rest. Basically, what I'm saying is that the N810 is a Linux pocket computer and I can make it do what I want. I don't need to be a developer, I don't need to pay a developer... I just need to know a little bit about scripting and how to rip through a plain old text file. This makes me happy. This is why I picked the N810.

Most of the N810 is like that... if you just think of it as a neat little computer, and are willing to work with it's quirks, well, it's a neat little computer. To make appointments, I put an action-item in my journal. Then, when I have time and am online, I post that appointment to Google Calendar as an all day event. Then, sooner or later I sync mcalendar up to this, and maybe edit the subject to include the appointment time. Why? Because it takes forever to make an appointment in mcalendar and because mcalendar screws up DST when syncing with Google, twice a year. Like I said, if you're willing to work with the quirks...

The only thing that really annoys me about it is how fast (and completely) it got dumped when the N900 came out. I mean, Nokia could at LEAST give us a flash update so YouTube is usable again.

I'm actually thinking about re-flashing again (first time in years) and I'm a little concerned that all the apps I use are still available. I mean, I depend on this thing for daily life... I'd really miss Dilbert and XKCD on the morning trip to the bathroom

You can blame that on Nokia handing out free devices at their dev conference, as well as providing cheap devices for active community members.

What i would have loved to see was a microb update that did not use the blow as molasses JS engine. Tho i guess i can live with webkit/tear.

Another long time lurker reporting.
I have N800 (along with my N900).

I am hoping to see the community SSU happening and people keeping this piece of hardware usable as long as possible.

I recently installed latest community SSU to my n800, advance-system-ui, new launcher, new fremantle like theme, easy debian and opera. And voila my N800 is looking and acting like a brand new device.

I can help on testing software and even a bit shell scripting / coding if anyone needs help.

Thanks everyone for hard efforts for keeping this thing alive for so long after nokia abandoned it.

picked my N810 in anger again after installing Diabloturbo - Vengenge edition. This has brought the performance right back up there, and reallh makes the device fly. in real terms it does not feel far of my N900 now.

Also installed the advanced system UI, also really cool and is a great addition to the devices.

these devices are great and hnave some advantages and features which the 900 has not scratched.

notably:
hardware task switch and full screen buttons
auto away on the IM.
a screen and keyboard of a decent size- love the N900 but sometimes its a bit small.

edit: forgot about
internet radio applet.
decent scrolling RSS reader applet

Does anyone know if the really old tutorials for installing to sd card still work? I'm thinking about reflashing my n810 so that I can try one of the turbo kernels, but I think the program to install to sd card was in qole's repo (and I'm not sure that it is still online).

I use N810 with MaemoMapper + topomaps in my enduro motorcycle as a navigator.

Search the threads for console tools. Penguin Baits tools. I just used them last night after a reflash to boot from sd. Also installed the diablo turbo beta. Yet again someone keeps breathing new life into my nit.

I still use my N810 on a regular basis. I don't have a smart phone or an iDevice so my N810 comes in handy often.

I use it to connect to wireless networks and although I haven't used it much, I can use Optimum wifi to connect when I'm out and about. I sometimes use it to listen to internet radio or as an mp3 player. It gets a lot of use as an emulator, letting me play Gameboy Advance games and SNES games (only with legal ROMs of course!).

At first I used the GPS, but now I never use it. I installed the community SSU updates and just downloaded the Klingon theme.
