I tried using a regular stylus on the Microsoft Surface, but that doesn't work; the screen is unresponsive. Is there a stylus available or does anyone already have good experiences with another type of stylus?
According to Paul Thurrott's Microsoft Surface: RT vs. Pro, a Specifications Comparison article:

As Karan pointed out in his answer, there is conflicting information on the Microsoft website and as well, other sources point to there being capacitive pens available for it.
From my experience capacitive pens are generally more like a replacement for your finger, verses a replacement for a pen. But I can't speak to the Surface's specific implementation.
Since you mention you have a Wacom tablet, then here a Bamboo Stylus from them that should "just work".
This is not a product endorsement, there should be plenty others by many other companies to choose from, none of which have I personally tried.

It will be available on the Surface that runs Windows 8 Pro, which is I believe is slated for release sometime in 2013.
The second link specifically lists:
This pen (with Surface Pro) will apparently be of the digitizer variety (similar to your mentioned Wacom), which should have the features and resolution more similar to what you're used to with your Wacom.
Capacitive pen means nothing but finger replacement, i.e. instead of using your finger, the pen tip has enough contact surface that mimics finger touch.
Inductive screen/active digitizer e.g. Wacom are actually screen recognizing pen itself as a special input device.
A few major advantages of having an active digitizer, but in short capacitive can not give true paper & pen feeling, whereas an active digitizer can (potentially).
So in the end, Microsoft stating that RT supports capacitive pen seems a bit misleading because any touchscreen essentially supports such as they are nothing but a replacement of your finger. But true underlying technology is not there to replicate pen & paper experience. So if that is something you are looking for, you have to watch out.
