I would agree with this as long as you have a decent LAN. We have about 60 computer workstations and 85 phones on our network. The entire thing is Gigabit. Each phone (with a few exceptions that we are running new cable to rectify) has a dedicated ethernet port, no sharing. We are NOT however separating the data/voice networks. They are on one VLAN. We may segment later, but only if the need arises. Right now we have no problems. I should point out that all of our switches have 2+ gigabit links back to the master switch. We've never had a problem with the phones other than related to the outside world (telco side). I won't argue that "best practice" would probably be to VLAN off the phones, but if you don't have a massive network and are fully gigabit smart switches etc with good cabling, then keeping the two "networks" merged should not be a problem. I do wholly recommend multiple drops per workstation though. In a day when I can buy CAT 6 cable for 10 cents a foot, there is really just no reason not to be doing multiple drops in new installs.
