I like contacts on ovi, but I don't use it all the time. It annoys me when I'm not using/signed in to contacts on Ovi that every time i open the contacts app it opens contacts on ovi by default.
It sounds petty, but if I want to make a quick phone call I want to be able to look up a number as fast as possible. And waiting for contacts on Ovi to load, then pressing across across takes precious seconds!
On the other hand, if I’m actually signed into contacts on Ovi and actually chatting, I do actually prefer it to come up first. So it needs to be a bit clever.
