A:Answer MS Excel runs lickety-split on Surface, even better if you let it auto-backup to OneDrive. You'll want the typecover keyboard as pen is more for annotation in MS Office and I'm often having to erase marks I left when I was just trying to edit cells, etc. with the pen; just put it aside in Excel. PS I've been using Excel Very long, having been early alpha tester for Microsoft developers in Seattle.
