I can see the attraction of this. Business systems are slowly becoming less dependant on legacy compatibility (our ERP and Finance systems are both now browser based and becoming browser agnostic) so that reduces the issues significantly. Setting up computers is a pain in the proverbial, especially with remote sites where I have to get the equipment here, get it set up then ship it out again. Being able to just place an order and have it arrive at the user's desk would be handy, especially if I can then forget about it.
There are huge buts to this though. Microsoft's reputation for cancelling services is a major issue. I already rejected moving to Office 365 due to the amount of admin work needed, I suspect having to administer your estate is actually going to be a lot harder than they admit. I wonder about the application install and config, e.g. are they prepared to install Acrobat Reader (answer, almost certainly no, "use Edge").
Definitely not for me.
