The cost for the 390 is really expensive. Id love to review one but for that price I can wait. Personally, I don't see a hugh difference from its twin sister the 385.
I think I'll wait on Vic to give us a peep of what's inside and if he can tell us if there is an improved battery circuitry. If all is well, then I'll glad to void my warranty and look at everything inside it
BTW, I love the colour and design.
