Even if the stick is lost or stolen, the data is safe. It can't just be plugged it into a different PC since it's password protected using BitLocker.
My take: That's probably the coolest thing for businesses yet! Unfortunately, it’s only available in Windows 8 Enterprise.
Windows RT to feature "Company Apps" and better business connectivity
Now let’s turn to the problem child, Windows RT for ARM devices. Obviously, Windows RT (which can't run x86 programs) has been declared DOA for businesses. Your IT line-of-business apps just wouldn't work. Is it a killer?
Well, apparently Microsoft doesn't think so: In tandem with Windows Server 2012, Windows RT devices can connect to a server and use RemoteApp to stream x86 software to ARM devices over the company network. Of course, you’d have to set up an entire Windows Server 2012 infrastructure to really experience x86 applications on these low-powered devices.
Next on the list is a feature called "TPM Virtual Smart Card" that is, essentially, a replacement for your SmartCard in a Windows RT environment. Using a built-in TPM chip, which Microsoft says is present and mandatory in every WinRT device, you can sign on to your corporate VPN using just the TPM module.
Finally, Microsoft revealed its "Company Apps" side-loading feature which admins could use to distribute corporate Metro-style apps to Windows RT devices.
My take: RemoteApp is a great workaround for ARM machines, but it all depends on IT's willingness to deploy Windows Server 2012 alongside Windows RT devices.
