Is it only me who's horrified by the fact they need a battery, i.e. upper left corner of this gutted picture:
As far as I can see, neither DS-Extreme, R4DS/M3 Simply needs a battery. Why does the G6DS Real need a battery (to keep saves I assume), when the others don't?
The reason I'm horrified is that I own a "G6 Flash" where a similar battery was used which went flat after a year - and it was a mess soldering on a new battery ... I'm actually surprised it's working after my soldering job ... yeah needed a bit of tape as well as you typically have a hard time tracking down these particular batteries with solder legs (as used in these carts) and trying to solder on the old legs is practially impossible (without potentially destroying the battery). If that wasn't all, the case broke so now it's taped as well ... looks awful and the cart is bulging as well.
Unless someone can tell me this battery is rechargeable (when DS is on), this is a definite stopper for me ... I'm just hoping they will have such a low price the others will have to follow (DS-Extreme in particular). It's strange, you didn't comment on this in the review.
