I\'m about to buy myself a SL-C750 (from pricejapan) and will need to order a charger I can use here in Sweden. Now, a USB charger sounds real nifty (seeing as I will always have daily access to a computer, and its one cable less) and they\'re even cheaper than travel chargers. Now, my quiestion is: Does a USB charger work all the way? I.e. can I use it for first-time charging, and for power while flashing the ROM, etc etc? Or do I actually need a normal charger as well?
