In so many ways I love the Surface RT. Yes, it is missing some very key apps, and can only hope. But I did purchase this for mobility and find it maddening that the current version of Internet Explorer is so very limiting and does not allow for WebEx or Go-to-Meetings. I understand the lack of apps but this is something MS can control now!
The problem is that for WebEx or GoToMeeting to work in the browser, they both need to install plugins and run executable files - this is not possible on Windows RT, period. The price you pay for consistently good battery life, and a user experience that is 'easy to use, hard to break' is that you can't run that kind of stuff.
Now, if Citrix (GoToMeeting) and Cisco (WebEx) or others want to launch Metro apps for their meeting systems, I think we can all safely say that would be very, very welcome! If you rely on these systems, then I strongly urge you to drop a comment or two to the aforementioned companies encouraging them to get to work!
