I'm primarily interested in photography and I do graphics more to satisfy my art side the anything else.
As has been said, stick to opentype. What I have been doing the last couple of months is converting my docs over to a Windows compatible format. I moved all my iWork docs to Office, my notes and stickies to OneNote and docs with fonts are next. I plan on using TypeKit fonts from Adobe Creative Cloud and also fonts that are in Office which should get me in the ballpark.
My plan is to keep my MacPro active for a while while I test things and transfer docs over. This way, if something doesn't transfer well, I still have the Mac available to correct issues. Also, I figure that there will be some apps that I might not find equivalents for or may take some time to find. Doing things in steps should minimize issues (hopefully).
