Windows RT does have rudimentary VPN capabilities built-in. However, the default Windows RT VPN cannot connect with popular, more secure VPN platforms like Cisco AnyConnect. Cisco claims that Microsoft hasn't provided the APIs necessary to develop an AnyConnect client app for Windows RT, and Microsoft has stated in forums that it is aware of the issue and working on a solution.
It is possible for the IT admin to configure Cisco AnyConnect in such a way that Windows RT can connect, but it requires weakening security in ways that negate the point of using AnyConnect in the first place. For now, though, the simple fact is that Cisco does have an AnyConnect app available for the iPad (as well as the iPhone, and Android tablets and smartphones), but there isn't one for the Surface RT.
Yes, it looks ridiculous when someone holds up a full-size tablet to take a picture or capture video. But if you're going to do it, you want to do it with an iPad instead of a Surface RT.
The front-facing cameras on the two tablets are very similar. However, the rear camera of the Surface RT pales in comparison to the iPad's. The iPad sports a 5 megapixel camera capable of recording 1080p video, while the Surface RT has a one megapixel camera that records 720p video.
One area where the Surface RT may be better is the placement of the front camera. The front camera is in the center of the tablet when used in landscape mode, which makes it ideal for Skype, Lync, or other video conferencing tools. The front camera on the iPad is in the center in portrait mode, but if you use the tablet in landscape mode it's off to the side so everything is skewed and off-center.
It should not come as a shock to anyone that there are more iOS apps than there are Windows RT apps; Apple had a few years of a head start. I'm not faulting Microsoft for not having hundreds of thousands of apps already for Windows RT, but the disparity of apps is a reality that businesses and consumers must weigh when choosing a tablet.
Many of the premier mobile apps are already available for Windows RT: Kindle, Netflix, Evernote, Box, Skype, and Angry Birds to name a few. However, there are also some glaring omissions--namely Facebook and Twitter.
