Sounds to me like a bunch of people unaware of available apps.
Depending on the length of the meeting, recording it in audio seems a far more efficient way to catch all the information--especially if you're keeping minutes. You can pretty easily follow that up with a speech to text app. I, for one, would not be trying to type notes on any device, not even a laptop, during a meeting.
#2 might stand up, but I do believe when Microsoft gets RT a little better integrated with the rest of the Windows environment that issue will go away for the Surface. On the other hand, if those iPad users had been using iWork on their Macs instead of Office, there's a good chance all those documents would have been readily available. I've found that document synchronization is almost completely automatic in both directions.
#3 is the fault more of your company's willingness to provide sufficient coverage. While I understand the desire to prevent outside access to the wireless network, if it truly affects the productivity of even one employee, the setup needs to be examined.
#4 is also questionable--showing more that either they or your IT staff don't know enough about accessing that Outlook environment, though I will acknowledge that the iPad uses several apps to serve the overall purpose which actually becomes more efficient as they don't get in each others' way. I've seen many an example where Outlook itself is the problem--alerting users to a meeting two hours or more after the scheduled time--on full Windows networks. As such, I can't really blame the iPad when even non-iPad users are affected.
