Forget the laptop, load the flash drive with your slide show. Using the new Toshiba DLP projector (TDP-EX20U) display 60 inches of visual goodness directly from your USB drive.
Get up close and personal with those 60 inches at just 2 feet, although wear sunglass as the Toshiba projector with USB has 2,300 lumens and an awesome 2,000:1 contrast ratio.
If you missplaced your flash drive, say dropped it in the water, then connect to the DLP projector via Ethernet or Wi-Fi. The TDP-EX20U is a cool $1,600.
