You can already access your Dropbox files on all your PCs and mobile gadgets, but what if you want to put them on your TV? If you have a Roku player, you're set. Roku has launched a Dropbox channel that lets you browse your photos and videos on its set-tops, including in slideshows. Yes, you now have an easy way to recap your vacation on a big screen without turning to other cloud services. The channel isn't flawless -- TechCrunch notes that you can't play long videos, so this won't work if you're trying to stream full-length movies. Even so, it's a big help if you'd rather not have everyone gather around your computer to see your snapshots.
