I agree. I just got Office 2013 and it's blurry as **** to the point where I can't type anymore and I spend all day in Work and Outlook. Office 2010 is nice and smooth. But I did have an interesting observation today when installed Office 2013 for a friend. I went up to his office and, to my great surprise, he had an old-school CRT monitor running on Windows 8 (his LCD broke). The resolution was, I believe, 1200 x 800. After installation, I fired up both Word and Outlook and everything, the text and icons, looked smooth like butter. Why? Also, I played with Surface Pro over the weekend, which is full HD, and Office looked smooth as well, unlike Surface RT. MS better fix this problem. Office 2013 is great but the text rendering makes it unusable.
CRTs don't need font smoothing. It's one of the benefits I've always loved about them. Surface RT has low pixel density hence the font issue being present (RT = 148, Surface pro = 208).
I too hate Office 2013's rendering. It's just inept. No options to control it and hardcoded into the entire suite. I bring that up because the new look of Office 2013, I could see Stardock or somebody coming out with an add on to make it look like 2007/2010, but there's no way somebody could skin away the font rendering.
