Having recently purchased a Nintendo 3DS I did a bit of digging when discovering it has an optional cradle charger. It's quite clever (in the simple sense) how they've achieved this, basically two sprung pins either side of the charge port on the cradle that make contact with two exposed pads either side of the charge port on the unit that are electrically connected to the Vcc and Gnd lines. No need for fancy induction charging at all.

I mention this because it popped into my head when reading the previous posts concerned about charging whilst in OTG mode. Rather than adding a separate charging micro USB port (whilst useful for availability of chargers wherever you happen to be), is the Neo900 not a fine opportunity to put some of the induction charging mods people have developed into mainstream use?

So the primary charge mode would be via induction mats, and this frees up the USB port for OTG, but to handle situations whilst you don't have access to a mat you could also support charging via the USB port, at the downside that as with the N900, whilst in OTG mode you wouldn't be able to charge easily without some funky cable solution.

Thoughts?
