I am returning my Surface RT tomorrow.
I am in the same position and I am seeing even bigger opportunities lost: about 300 users depend on my opinion on such devices, even for their own personal or BYOD purchases.
Those who have asked me (and have played with my RT, and have loved the keyboard and everything else...) now won't be buying it, simply because I told them they can't connect to anything work related... A lot of Christmas shopping opportunities lost.
I hope Microsoft realises that word-of-mouth is an important part of marketing for these new devices at launch and that they shouldn't fire their Windows 8 top exec over eliminating the start menu (which is no big deal, actuially), but may be over restriciting Cisco, Juniper from providing VPN apps on the RT variety?
And, if they intend to allow Cisco and Juniper to make VPN apps for the RT, they should announce it right away, even if we have to wait for the actual implementation.
