HP has just made either the most hyperactive digital picture frame on the market or the lamest tablet PC ever. The DreamScreen looks sort of like what you’d have if someone tore an HP Mini in two and handed you the monitor side. It’s a device that can run video, show pictures and play music with built-in speakers. It has USB ports and it can hold 2 GB of data. There are two models: one with a 10.2-inch screen and one with a 13.3 inch screen. So far it sounds sort of like a giant personal media player.
