In the summer I switched to using Windows Phone 8 and Outlook.com using a Lumia 820.
So far I am very satisfied with the phone and the software. Windows Phone provides a great customer experience!
Here is a quick list of positive and negative aspects:
Positive:
- people-centric interface - finally, the contacts are all in one place
- Skype, Facebook, LinkedIn integration
- pin anything to start screen - including the pictures of your friends to keep track of what they're up to
- make notes and share them with PC, Mac and iOS with OneNote with cloud sync
- free Adobe Reader allows PDF comments
Negative:
- interface relies too much on text - a few more icons wouldn't hurt
- too few official apps - Dropbox, etc
- some interface disconnects - for instance, in the SMS menu there is no way to call the person
I recommended the following (paid) apps:
