Prefer to travel cross-country by rail? If you're an iPhone owner, you no longer need to fire up a third-party app to plan your trip. Apple Maps has introduced support for Amtrak train routes across North America -- if you want to navigate all the way from Los Angeles to Toronto while seeing the sights, you can make it happen. You'll need to live in an area where Apple's mass transit directions are available, of course, but this remains a big deal if you're more interested in how you travel than the time it takes.
