The first reviews of Surface RT are in, and they are not good (see http://www.businessinsider.com/bad-surface-reviews-2012-10 for an overview). I ordered one, despite the initial disappointment about the specs (especially the screen resolution).

Of course I will pass a final judgment only after I have experienced the device myself (I have an iPad 3rd gen so I will be able to compare), but currently I´m a little bit worried about Windows RT/8 tablets in general, because Surface is such an important device in this category.
