Some places in the USA only has that speed!
If ALL traffic and work is going over an outside connection - and now your WHOLE business depends on it being up or nothing gets done - the business now has to have multipe ISPs and paths in order to have a failsafe fallback.
Not all will require it - if your 20 member firm can live for a whole day - or two - without having access to any data at all and still make money and the workers can still work - then going this route is okay. But if the whole business grinds to a halt due to an outage (rare yes, usually 2 to 4 days a year) then it is back to the basic cost benefit analysis that always should be done. Can a business afford to pay out $12,000 for 60 people doing nothing for each day it is down ($200 a person a day) for 60 people?
I think these, like ANY THIN CLIENT, works for a vertical web only application. If a person does multiple jobs / functions and uses more than a basic MS Office type job, then it tends to cost more in hidden costs that are NEVER looked at by any analysis - or else people would see the true costs and never go to it.
Also, with all going outside then the link to the Internet will have to be upped to something a bit highter than just handling e-mail traffic to keep response times reasonable.
