I bet a lot of you either have Comcast, DirectTV or U-Verse. Me? None of the above. All I've got is a laptop, an HDMI cable and flat-screen plasma TV. I can stream my Netflix or my Hulu account from my laptop onto my TV. Or watch a DVD. Or I can surf the web on my big screen. Or I can slideshow my favorite art while I play my iTunes during a party. Just one example how I use technology to save money.
