I've been a happy owner of an Apple MacBook for about two weeks now (something I'll write more about soon). Having both a desktop computer and a laptop means you need to make sure a lot of things stay synced. For me, the most important things are files, email and browser bookmarks. I use IMAP* for email so that's already taken care of but syncing files and bookmarks requires extra software, and I found just the right applications for the job. Best of all, they're both free!
