l have a SX20 and after 3 years it feels like it is getting worn out so l was waiting to buy the SX40 as a replacement, which l will not as just like the SX30 it runs on a IONLithium battery and not AA's. For me a bridge is a travel camera. This year l have spent 2 weeks in the Sahara and 2 x 2 weeks in the Himilayas in both cases there were no possiblities to charge batteries, which didnt bother me as with the XS20 l use lithium AA's that allow abt 1500 shots. l have now bought a Fuji HS20 (uses AA's!), but l don't like it's handling. Could Canon PLEASE make the XS50 for AA's. One last remark for those who want RAW on a bridge. My HS20 has it and uses abt 15 seconds to calulate a RAW shot, so no travel camera. It can only do this because of the manual zoom elec.consumption is low, but for a traveller it's a useless camera as you can't make fast situation shots of people and movements.
