Hugely overrated

I got this following some rave reviews and am disappointed to say the least. The design is a matter of taste but nothing beautiful for my buds here, definitely not standing out of the crowd. What bugs me tho are performance issues. I missed a couple of tel-cos due to app failing to remind me. Also integration with my wifes calendar sometimes works sometime does not. I got this before it was acquired by MS and it seems to be getting worse lately - is it possible they destroyed a good app?
