Looking to spend upto 700 max. I saw a few in comet (newport) today. Sony VAIOs at 650 with 4GB ram and 200GB hard disk. But they were discontinued models so I didn't know if they would be good. I also saw the acer one with a massive screen but thats much too big to carry round. Does anyone know how good the playback through a 1080p tv is when one of these is connected through HDMI?
