I just got an A3000B from amazon.co.uk. -Remaing time is displayed be default. -Connect player software allows drag and drop. You can't drag and drop from (say) windows explorer. -I havn't had it long enough to find out. I would be very very surprised if I had this problem other than if I bumped into someone. -Atrac 128k gives 28 hours, Atrac 48k gives 35 hours ( these are the published numbers) -when its charging its not cold , just gently warm. I would describe it as a cup of tea which has stood for 10 minutes. - I would add it has a nice weight, very solidly built and the menu navigation is very easy to master.
