Desktop architect here with a user base of 350ish.
We've deployed 60 Surface Pro 4s this year to DRP folks with docks for their desks and VPN capabilities for home. We've seen our helpdesk volume bump up expectedly as a result, but have yet to see that normalize. My feelings for the Surface Pro 4 are still a bit 'meh', I was gung-ho to buy one for myself at the beginning of the year, but after using one professionally for the last 8 months and deploying the rest to other users, I went with a traditional laptop instead. Too many flashy features for an enterprise device and I'm not a fan of flashy features for my personal devices.
And I wasn't even logged in. The above is my comment.
