What about the Power supplies? With all the different destinations with their differing voltages and plug types, is it going to be some universal device or one specific to each zone?
Like the PSP charger, I imagine the Pandora charger will use a standard figure 8 adapter. It'd be cake to simply replace the cable then. I've little doubt that any computer store worth it's salt would have the right replacement cable for cheap. This is at least true in North America and the UK, but see no reason for it to not be true elsewhere. It's an international standard.
Would it blow up if it's connected to 220 power? I've lost too many of my good electronics to forgetting to use a converter (and instead using only an adapter). I know most modern laptops can run on both voltages.
