having played with this a bit today....some first impressions (and now i am on my laptop so it is easier to type (any typos are mine not the nokia's)

it feels smaller than my 770 and sturdier - maybe the difference between titanium and black plastic

it is absolutely zippier both on the web and apps on the machine

the new 2008 interface is much more "user friendly" it reminds me of the difference between my old win98 interface and my current osx (tiger) it is definitely "prettier"

i do not see any functional difference between the interface from 2007HE and 2008

operating system wise i like 2008 better eg it looks like you can now import bookmarks whereas on 2006 and 2007HE you could not import bookmarks-- nokia has some interesting sites bookmarked which i will explore later and i am glad i do not have to overwrite them to get my bookmarks on the tablet

more later when i have a chance to do some more with the tablet - but in short as of 1 day w/it = its definitely a keeper (the gps is fantastic- it is the only gps that has found my house where it should be- google maps my garmin all have my house about 100 feet east of a service drive when my house is directly west of the service drive- waypoint found me correctly...
