There are some things I don't like, I'm used to dedicated servers and I miss things like scanning the eventlog looking for where my stuff screwed up (could handle it on the front end but meh, the eventlog's so convenient!), but overall it's quite awesome.
I really hope they manage to package their stuff up so it can be installed on other servers.
Sure, someone could go and write about those companies anyway, but they wouldn't be invited back.
I also think the concept is very appealing to restaurants as well. Adding value for everyone seems like a sure win to me.
