After a rather late (or more accurately early) night, I was awoken by a text from my friend asking when my Nokia N800 was arriving. I forewent answering him in favour of more sleep, only to be woken again, but this time by a delivery man with the item in question.
After upgrading it to OS2008 (thanks mrben), I started playing with it properly. So far I’m loving it, but I’ve not done that much with it besides surfing, mail and Skype but then it is an internet tablet.
Things I would like to see:
Being to synchronise contacts with my N95 or Evolution The webcam being supported by Skype/Flash
Are there any apps I should check out?
On a semi-related note yesterday I debranded my N95 and updated it to the latest firmware.
Oh, and of course this was posted from the N800! 
I have gizmo project installed on mine. This lets you video call other clients on the maemo platform or with the windows beta of the software
How easy was it to upgrade to OS 2008? I am seriously tempted, but I have to buy a new desktop first…
Conduit (www.conduit-project.org) is working on a port to maemo. That should be able to handle your sync needs.
Mattj: it was easy for me, using the instructions at http://maemo.org/community/wiki/HOWTO_FlashLatestNokiaImageWithLinux
(I tried the Windows updater first, but it took hours to try to download the update and then timed out.)
….and this one is posted from an ipod touch
Apps to check out? FBReader for e-books. Maemo Mapper for maps (although OS2008 comes with its own non-open-source Maps app that I haven’t tried yet). Maybe Canola for a media player with a slick user interface? Openssh-client if you’re a geek/sysadmin.
I’ve not checked out which apps have OS2008 versions out, but definitely take a look at:
Maemo Mapper (as mentioned) - particularly as it has openstreetmap support
Canola looks really nice, but (as mentioned) isn’t Free
ScummVM for some point ‘n’ click goodness!
If you’d like calendaring support, then GPE Calendar combined with Erminig will do a 2-way sync with Google Calendar, which is pretty cool.
