I also experienced the same trying the latest Nokia codedrop image....
it is really slow because it running from the mmc but well it starts to work mostly...
the statusbar (battery indicator, ... ) still doesn't seem functional, xterm isn't working as well as power off and such stuff....

still LOTS of polishing and feature development ahead.... but we are on the right track =)
a navigation solution would be great... afaik OVI maps API is exposed via the qtmobility framework... so this should be possible...
or will we get OVI maps as soon as meego becomes really production ready?
