Have you heard of UltraViolet? It’s a digital service that allows dads, moms, and kids to upload, store and watch their favorite movies whenever and wherever they want. I tried out the service recently with three of Sony Pictures’ UltraViolet movies: Men in Black (I and II), Moneyball, and The Girl with the Dragon Tattoo. The movies were great on my Blu-ray player, but I also loved watching the UltraViolet movies on my iPod touch and Nook Color. The playback was very smooth. Best of all, I didn’t have to use software to convert my movies into a format that can be played on my mobile devices. The cloud service took care of that for me, and the process was easy and very quick.
