The N-trig pen may not be as bad as everyone is predicting...
A small transcript from the Engadget hands-on:
"More important than the higher pixel count, perhaps, is the new pen tech. With this generation, Microsoft ditched Wacom and instead used an N-trig active digitizer. We know, we know: This probably sounds like inside baseball to all but our most hardcore readers. In truth, though, it's a better experience. The pen, first of all, has been redesigned so that it feels more like a normal, ink-based pen. Indeed, it does feel more substantial in the hand, not that I had many complaints about the pen that came with the Surface Pro 2. Also, the screen has just enough friction that when I write on it, I feel like I'm writing on paper (or as close as you can get, anyway). On the software side, Microsoft's own OneNote app now sends your scribbles to the cloud as soon as you lay them down -- yep, kind of like how Google Drive or some such will save your work as soon as you start typing."
Hope this gives some solace to the complainers
