Sources say HP was not happy with the overall performance of Windows 7 on their unreleased tablet, saying the OS was too power-hungry. Additionally, a Windows 7 license will bring up the price of any final Slate product, and now that HP owns WebOS, the move makes sense.says also that HP is set to drop the Intel processor used in the tablet, which would completely kill off any chance of Windows 7 being used.The Slate, in its original state, would have run on Windows 7, would have been $549 at its cheapest, and had an 8.9-inch 1024x600 multi-touch screen. Additionally, the tablet had a 1.6GHz Atom Z530 processor, 1GB RAM SDHC slot (with support up to 128GB), two cameras, a USB port, a SIM card slot, and five-hour battery life.
