According to The General, it seems we are all newbies and should just go away. Sorry dude, but your attitude in almost all of your posts (that I have read, and I have read quite a few) is negative or obtuse towards the poster.
Please attempt to understand the pure ignorance on some users' parts. There is no need to be on the offensive until you have been offended.
And for your retribution's sake, please remember that I have not been in this forum posting for more than a day myself. Fortunately in my defense it shouldn't be any trouble dealing with anything you can dish up. (Now who's on the defensive?)
Anyway, back to the thread at hand. Great idea as I was about to start one myself but did a search first

OS2008 on the N800:
Pros:
Sexy interface and desktop themes (really nice clock too).
Skype works perfect here.
Radio and Camera apps work great.
Canola 2 works, with minor caveats.
GPE Calendar works.
Browser works better, faster, and with lots more support.
Device feels faster than OS2007.
YouTube Works, fast! So does webmail/online banking/webadmin GUI
Map application included (cannot get the map files for east coast).
More finger-centric menus (but finger-centric menus do not extend to app menus).


Cons:
Finger sense for thumboard seems crippled.
Browser says "connecting.." at lower right sometimes but never does. This could be just my device hanging.
Repositories are not responding properly (not OS2008's fault).
Less application compatibilities, for 2k7 only.
