I’d been using Office 2013 Preview since August, and, while there have been hiccups here and there, I’ve been very happy with it. Last week, the RTM version was released to MSDN subscribers. (I think it will not reach general availability until Q1 2013.) I was excited to get my hands on it, so I downloaded and upgraded right away.
My only disappointment in the upgrade experience is that I couldn’t go directly from Preview to RTM, but that wasn’t completely unexpected. I uninstalled and installed the new version. Everything went smoothly.
I’ve been using it for a week now. I haven’t noticed any new features in the RTM version that weren’t in Preview, but there are a few “quirks” that have been fixed. The biggest bug that I’d been dealing with in Preview was in Excel: when you clicked a drop-down in a cell, the options would display in the upper-left corner instead of at the cell. This has been fixed in RTM. Another gripe I had in Preview was about the read-only, “Preview Mode” version of Word that opens when you open a Word document attachment from an email. This is still there, but pushing the ESC key takes it out of Preview Mode and back into the standard, edit view. So that’s good!
Everything else has felt really polished and very slick, and I haven’t seen anything that I’ve perceived as a bug, flaw, or unintentional.
I’m definitely loving the new version!
