For a tablet-focused event I don’t think you will find much disagreement that Microsoft has hit the mark with Metro. Metro feels like it belongs when used with a tablet – it’s smooth, it’s easy to use, it’s gesture-driven, and it’s finger-friendly. Virtually everything Windows Phone 7 did well as a touch screen OS has been ported over to Metro and it shows.
The converse of that is that Metro feels awkward and out of place when used with a mouse and keyboard as a laptop/desktop. It fails to take advantage of the precision of the mouse or the fact that not everything needs to be in size 28 font when sitting down to use a computer. At this moment it feels like trying to use a tablet with a mouse and keyboard, which isn’t far off from what it really is in the first place.
Sounds like a winner.
