Excellent write-up. WoW was definitely eye-opening w.r.t. Analytics on the platform. I've played around with Box and the integration as well as the mobile offerings. Not real use but just a side project thing. Those look promising also.

I think the workflow engine they just added will be another valuable feature

I'm not sure what you mean when you say no sync for non enterprise. I use Box Sync for my free personal account, both on windows and my mac, as well as my iPhone and Android phone
