Had my HD5 for a few days now and slowly getting used to it although I must say it's a bit of a culture shock coming from 3 years with an Archos Jukebox which was pure Drag-&-Drop. A note to Sony: Please wake up and get a grip on what the customer wants. It's taken you this long to realise that, whatever the merits of ATRAC, MP3 compatibility is ABSOLUTELY 100% OBLIGATORY, your sales figures will confirm it, so take the next step and make it user friendly ! Anyway back to the HD5, I have applied the volume hack and thank goodness for it because before it I was starting to think I'd made an expensive mistake. Happily I found the Drag-&-Drop proggy too which, despite it's limitations, is extremly useful. Also have had to re-encode some of my MP3's because SS refused to transfer them even though they worked fine in every other device/player I ever tried, what's that all about ? I have 1 question if anybody can answer it: In the options menu what does Unit On/Off do ? I'll write more about my impressions in a few days when I've had more time to evaluate the beast.
