I am playing catch up learning about the new features in CRM 2013, so I was googling around and there are lots and lots of blogs, youtube videos and sites with information.
Then I saw a blog post by CRM Super MVP Donna Edwards has posted a fantastic blog post called getting ready for CRM 2013 and it basically contains links to blogs, technet and lists all the partner source videos
for those who don’t have partner source access but still want to watch a video
here is an hour long video from microsoft about the new features in CRM 2013
also here is another good video about the new features
I’m sure there are lot of other sources of information but I am going to work through these first before concentrating on specific new features in CRM 2013
