With regards to the above players, does anyone else find the stated battery lifes quite suspicious? ~ Sony Vaio Pocket VGF-AP1 - 20 hours ~ Sony NW-HD1/3 - 30 hours ~ Sony NW-HD5 - 40 hours Notice the pattern?! It seems to me that Sony are either limiting the battery life of the players to those nice numbers (unlikely) or are rounding up/down the stated battery life. Almost certainly rounding up, wouldn't you say? It would be an extraordinary coincidence if that is the genuine maximum battery life for the individual players!
