Ditto here. I just moved a friends primary domain from GoDaddy to Namecheap a few months back.
A month ago I had his other domain's MX records pointed to a domain on Namecheap so he's mostly still up and running (except for a few GoDaddy hosted subsidiary sites).
I personally don't like GoDaddy. I don't like the endless spam from secureserver.net and I don't like their support for anti-Privacy bills in Congress (CISPA). -- Campaign contributions influence laws through a process called bribery.
