I reluctantly tried the new version of WHS. I really didn't like that they removed the pooled storage. Once I got it up an running, I quickly retired my V1 WHS. The removal of the drive extender has been a non-issue for me. The new product is much quicker than the old. The other features such as remote access are much better. The server backup feature is very nice.
I have not tried to do a bare metal restore in this version. I did do it many times with V1 successfully. I haven't had a need lately.
Just my $.02
