1. I've been using google reader mobile on my cell phone for RSS feeds - getting used to the interface, although I still prefer NetNewsWire Lite on my Mac (with Newsgator synching).
2. http://www.vox.com looks like a nice featured blogging host, with growing mobile features.
3. The Google synch plugin for Firefox is a great way to synchronize bookmarks and settings between Firefox on multiple computers - very similar to .Mac synching for Safari.
4. The Apple iPhone looks very cool - could be the perfect UMPC device for education!!! (especially with the uptake of podcasting in education already...)
