Sufrace RT or Surface Pro? (For IT administrators)

Hey Tribers!

I am an IT Engineer, and would like to get one of those slick tablets from Microsoft. As you probably know, Win RT doesn't run old legacy apps and will not have any Domain compatibilty (No Active Directory etc..).

So the question is

1) Will there be any ARM based metro apps from Windows Store which will provide any administrative functions to administer Domain (AD) etc..?

2) Or, what do you think, maybe there will be 3rd party apps which will run on old Desktop Mode (just like built-it Office) to provide such functions?

What do you think?
