Sure, you can use Apple's own Remote application to use your iPhone or iPod touch as a remote for your Mac, but that likely isn't going help most folks' with their home theaters. This new L5 Remote might be just what you're looking for, however, and it doesn't require a pricey dock like some other similar options. Making its official debut at CES, the L5 is a $50 IR dongle / app bundle that promises to do more or less everything that a dedicated universal remote does, and plenty of things that many of those don't -- like let you create your own customized interface. Of course, that all hinges on the thing actually working as well as a dedicated device, and we should no doubt hear more about that in the lead-up to its rollout next month.
