I'd like to know why my pictures won't migrate to the Photos app but otherwise I'm having a blast.
Once I got my head around the Metro layout and where the important stuff is, I found it really simple to use but it's the speed of things I'm liking as I have it running on an old Dell Inspiron 1520 with a crap Celeron processor so I was pleasantly surprised it loaded at all.
The boot time is impressive and unless I'm mistaken, this OS seems to leave less of a footprint on my C drive than Vista or 7 ever did.
I'm just waiting for the next generation of devices when the OS is finished and it's available on a hybrid laptop/tablet. Yummy!
