The SX40's "very expensive" battery is the NB-10L, which can be bought for under $20, measures a mere 1.5 x 1.4 x 0.5 inch, and weighs 1.3 oz (36.8 grams)

Four AA batteries, on the other hand, take up more space. As for weight, the average weight of AA batteries is:

alkaline AA: 23 g
lithium AA: 15 g
rechargeable NiMH AA: 31 g

So four AA batteries will weigh from 60 grams to as much as 124 grams, compared to the 36.8 grams of an NB-4L battery! If you're using four rechargeable NiMH AA's, you're talking about more than triple the weight of a single NB-4L! Almost 90 grams in additional battery weight alone. Camera bulk might have gone up for any particular camera, but it certainly isn't due to the use of a proprietary battery. On the contrary, the use of a proprietary battery keeps the weight and bulk down . In other words, if the SX40 still used four AA batteries like the SX10, it would be even bulkier than it is now! Nice try, dona2. LOL.
