Formatted for the 30-inch display, it measures a whopping 2500×1600 pixels, and is sure to make your Mac look futuristic.

While Apple just have announced the iPhone to be released on June in the USA, LG already released its superphone: LG KE850 also known as LG Prada. And even if I do love Apple products I must admit it’s the first “touch screen mobile phone”The KE850 PRADA’s UI is Macromedia Flash-based and opts for a minimalist, white-on-black display as opposed to the more, shall we say, OS Xish GUI we’ve already seen floated. Feature-wise, the KE850 comes with a video player supporting MPEG-4, H.264, and oddly, H.263 normally used for video conferencing; a document viewer supporting Microsoft’s PPT, DOC, XLS formats, PDF and TXT; an audio player with support for MP3/ACC/ACC+/WMA/RA formats; and a “music multitasking function for messaging,” whatever that is. How much? 600/$778
