1. does it have video bookmarking like an ipod? meaning if you are watching one video and pause at 5 min 23 sec, then go watch another video, can you back to the first video and have it start playing at 5 min 23 sec?
2. Fast Forward & Rewind - does it jump every 10 seconds or so or can you be very accurate to the second?
3. does it have an equalize or presets to get the sound how you want it?
4. how is the overall sound quality, will it replace an ipod?
