Been tempted to get one of those newfangled multicartridge systems, so I can have a one machine solution under the telly. But I'm a bit put off by the way they make such a big deal about 720p upscaling. Apart from the general rubbishness of the boast (has anyone actually got a 720p tv?), I was wondering if this causes probs with a standard 1080p tv. Does the extra upscaling the tv has to do cause extra lag? Thoughts plz...
