WSE2012 should come close to the plug-and-play simplicity of WHS v1. Storage spaces should be superior to WHS v1 DE - you can set up multiple pools, you can choose folders to have duplicated on more than two drives for extra safety, and it supports drives of different sizes. But you wont need WSE2012 to get it, Win8 will have it.
Win8 also has a file versioning system to allow quick recoveries, and you can store the version data on a separate machine, so some people are considering using Win8 alone as a replacement to WHS!
