Installed, played with it a bit… Looks nice 🙂
Among significant pluses(IMHO of course):

  • smoother experience
  • nice improved and thought out UI
  • sms log deserves additional applause (clap)(clap)(clap)
  • back(PC->phone) synchronization improved(both speed and reliability)
  • working(at last) maps(NavTech)
among things I miss:
  • full control over the phone’s file system
  • application install
  • media(other then mp3) transfer
But for those the are great news: Good ol’ PC Suite is not removed with Ovi upgrade 🙂 So you can still use it if you wish to…
Generally Ovi is a much better tool for daily sync then PC Suite was. I literally enjoy using it. And most of the PC Suite functionality preserved.
I didn’t use the Ovi store – the main purpose of all this thing :):):) but I used maps service and it is pretty decent. Keeping in mind that you can download the maps for different regions and upload them to your mobile beforehand makes it a very useful thing, specially if you have a gen5 Nokia.
