The cost of these additional servers can be excessive.
First of all, sorry for the late reply.
The IT staff saving from using thin clients is 100 to 1, if not more.
After things are set up, a 3-person IT department can maintain and support thousands of users.
How many IT staff do you need to support thousands of individual boxes?
Can their salary pay for 3 persons?
This is proven and applies to any industries, including this German publisher.

Network bandwidth is not really an issue.
Unless everybody tries to watch YouTube at the same time, the bandwidth usage for normal office use is very minimal because the screen data is compressed and only the difference is sent.
In my previous company, everybody used a Sun Ray with Solaris (even the receptionists), and the Sun Ray only supported 100Mbp Ethernet. Nobody felt any slowness or lagging.
Other companies that I have been at mostly used VNC to connect to the server. Same thing. No network issue. Only plain 100Mbps Ethernet and switches. Using VNC is like using a Sun Ray; the only difference is people are used to the desktop so they don't care if their desktops are just acting as dummy terminal clients.

Man, you definitely can't argue about the cost.
I agree, some cheap PCs may be cheaper than thin clients. But you need to factor in the power usage of a PC vs a thin client.
How much power does one typical PC under normal load consume? 100W? 150W?
A Sun Ray only consumes 4W.
That's at least 25 times saving in power bills.

Like I said, there are pros and cons here, but I don't think a blanket statement of 'should have' is a valid assessment.
That's why I said their CTO do not do their homework.
We should convince themselves that thin clients are the correct way to go.
Especially this German publishers. When they have the budget to replace all PC with Mac at once, they don't have that rather-spread-cost-over-quarters excuse you mentioned.
Buying 12,000 Sun Ray + some nice PC servers could not be more expensive than buying 12,000 Macs + new Mac servers.
Besides the above benefits, there are plenty of other benefits from using a Sun Ray. Portability is one key benefit. Once I worked for the company that used Sun Ray, I really think there is no better technology that is as cool. I can go to any conference room or other people's office, plug in my badge, type my password, and I can see the exact same desktop session. It works even across multiple campuses and even countries.
My school has a PC labs, and every time I switch to any PC, they have a stupid script that takes a few minutes to copy files over so that I can see the same "My Documents" and other personal stuff. This only makes personal files portable; not the desktop session, i.e. I can't leave my Word open and switch desktop. Session portability is one thing a PC can't have (of course, using VNC on a PC doesn't count).
Another thing is security. There is just nothing to steal and nothing to break. Nobody can steal any data from the thin client, and there is no hard drive, RAM, motherboard, fans, etc so you rarely need IT staff to come over to fix things when they break.
The Sun Ray software supports all major OSes including Windows and OS X, so if that German publisher really wants Mac, they can still choose Sun Ray over 12,000 Macs. Again, unless they need to do video stuff, I really don't see any reasons why they should choose Mac over thin client.
I may seem like a Sun advertiser but honestly I am very impressed by their Sun Ray thin client. I still miss the days when I can just run into my co-worker's office, plug in my card, show my screen and prove that he has made some mistakes. It's a really good technology. Every time I go to a library and see those Dell PCs sitting there for people to search catalog, I always think of Sun Ray. Why do we need a power-hungry Pentium 4 with HT, a CDRW drive, and the bulk chassis for a catalog search / Internet access machine? There is no better places to spend our tax dollars? These are also the examples that the IT staff do not do their homework. Too bad, either Sun's marketing is not doing a good job or people just don't want to change their habits. Just like here we all know Macs are better, but when we need computers, the IT guys will just automatically log on to Dell web site and order PCs.
