Re: Pointless?
Yep. You'll lose most (if not all) of the audience when you state "roaming profiles", because the way MS implemented it (and still has implemented it) is a bandwidth sucking dire pig trying to pull a ~200 litre drum of molasses through a very small straw.
The primary around that tar pit is VDI, in which case you are using the chromebooks as nothing more than RDP clients to a giant bestial cluster of server nodes with fusionI/O cards (or other such on-node storage accelleration) or running vSAN (or are nutanix boxen)
in which case you are still a prisoner and beholden to the Dreaded Backhoe of Doom in case the network connection gets whacked.
