Ok, so I'm in the market for an upgrade. I've narrowed down my choices to the A80 and G5. I've read reviews on both and they both seem to be great. But I haven't really seen anything that compares the two. Just judging by price, I assume the G5 is "better". Can anyone tell me what the pros/cons of each are? It seems to me the battery situation in the A80 is probably better since they are AA and can be replaced easily. But maybe even that's not right. Any advice would be much appreciated.
