I don't have a touch screen on my pc, but am running Windows 10 Tech Preview, so decided to download the beta version of Word.
I'm pretty impressed. It's simple, smooth, and has all of the features of Word that I'm used to using in Office 2010 (I have 2013 but haven't installed it).
I also have a Windows Phone, so am looking forward to testing Windows 10 on that as soon as the tech preview is released. The touch versions of the Office Suite will be making it into the phone OS as well.
