A belated welcome aboard Bryan and great intro and discussion. I'm going to move it over to the general business forum as it's pretty interesting.
I'm a bit late to the discussion, but thought I'd add my five pence worth.
Why would a small business's want to risk totally working in the cloud?

I've been a long time cloud cynic after watching the awful early implementations and still have reservations about it in certain areas. But Cloud infrastructure technology is maturing, single points of failure seem to be disappearing and techies are becoming more competent in configuring and partitioning cloud storage.
I put my our business toe in the cloud waters by moving our email services to a cloud provider a few years ago. Far cheaper and more reliable than the old mail server in the office.
But I've always resisted moving heavy database driven websites to the Cloud and a recent migration experiment failed, so we remain with dedicated servers at Rackspace. But plenty of huge websites live in the cloud, including the likes of iplayer which uses (I believe) Amazon Framework Services, although they do have a wobble from time to time.
But phones seems a much safer bet and we have been trialling for 6 months a VOIP Cloud service from Vonage. On the back of this we have just replaced all of our office phones and are now using Vonage VOIP cloud services. The cost is a lot cheaper than our old fixed lines, plus we have a mix of high volume call packages and low volume, which work out a lot cheaper than our old landlines. Plus we get a lot more functionality (for free) such as HUNT groups, diverting to a mobile and using your mobile as your landline (ie landline number displayed).
It's still early days, but am very impressed and slowly warming more and more to this Cloud malarkey. I can see why the stats say more business owners are moving to the cloud, particularly smaller businesses. You can give a big company smoke and mirrors perception for minimal cost with a very flexible and configurable solution.
Residential houses and businesses in the near future won't have any copper wire connected to them, but a direct fibre link, allowing this to power all comms from phones, to internet of things, ie smart devices such as TV's and Fridges! The plain old telephone system (POTS) and public switched telephone network will be consigned to history, even though arguably it's more reliable as POTS will keep going even if you have a power cut (due to the line being boosted by batteries). Something your IP phone won't do!
