ESRI is rolling out ArcGIS 9.3 in seminars around the country. Good stuff. There was a great map exhibition at the Walters Art Museum in Baltimore, MD this past summer. Old, spirtual, fantasy maps, etc. Along the lines of old and new, another great collection to see is David Rumsey's historical maps rendered in Second Life. A preview is posted at the Not Possible in Real Life blog.
I love the new GPS travel community contribution pages like Everytrail. I'll need to invest in a fancy GPS like Garmin Edge 705 for the bike to get this thing going for my excursions.
