Surface RT, what a kludge job! Tablets are mainly about time wasting and media consumption. You need the MS Office Suite for that? Tablets don't have keyboards because they don't need them, see time wasting and media consumption above, so the Surface ads all feature the dancing tablets with the click-on keyboards.
"No, no, no, professionals want tablets and need to do useful work on them", you say? I say, way too few pixels on the screen, which is too small, and oh, right, the Surface RT can't run real Windows programs anyway. "But, but there's a Surface Pro for that", you say? I say, for a $1000 I get get an Ultrabook or a MacBook Air which is what your Surface Pro mimics poorly at about that price with its keyboard attachment. Oh, and I don't like my tablets with fans anyway...
