We are a 40 person organisation and use S4B via our Office365 subscription. It works perfectly.
That said, being in Australia we don't have Microsoft-provided telephony in it, nor do we have any requirement for hunt groups and so forth. All our staff use their mobiles to talk, so Skype is purely used for teleconferences and video chats.
Enterprise telephony is a weird space right now - Microsoft ought to emerge the winner eventually with their broader stack proposition, especially when compared with most other vendors that try to stick in their bloatware or poorly written software. But gee it is a painful and slow transition to observe from the sidelines.
Serious question - what is so compelling about S4B.
Competition is very healthy in that space, last time I looked at Lync etc it was seriously lacking.
It's just the convenience that is compelling. If you already use Office365 the integration with outlook for web (and desktop for that matter, which I rarely use) is really neat and for the most part "just works".
I've got some seriously non technical people in the business who find it super easy to now arrange a conference call, when previously they would be using their iPhone on speakerphone to merge calls.

Just my 2c. :)
