EvanK - When the S90 was released, before the S95 - friends and I here were surprised to see that such an expensive P&S doesn't have something as basic as a P&S-style EVF... Just looked at Sydney pricing on the S95 - AUD$509.00 (same as USD - they're at parity at present) - which isn't unusual, as cameras and accessories are 35-50% higher than US prices here.
But that seems to be the style with P&S cameras these days - most Makers seem to be minimising on "working" features, and replacing them with the much cheaper software "gmmicks" functions... A $500.00+ camera without a viewfinder is rather like a $50,000.00 car that has no seats... That is - at that price, you expect to get some seats - however basic.
A lady friend of ours "liked the features" of the S90 when it was released - then discovered - no viewfinder - and no AA batteries. End of sale - she bought a rather cheaper Fuji that has both.
It might well be that Makers assume that people buying under-$500.00 P&S cameras are all young folk with rock-steady hands when held at arm's length - and perfect eyesight to see the now usually 75mm / 3" LCDs at that distance. And that the "very few" people over 50-ish who buy P&S cameras - will pay over $500.00 to get a Bridge Camera or DSLR with a viewfinder....
There are actually people under 50 who wear glasses - even some teens and kids. The younger ones can hold the camera steady - after they've changed their glasses to get a sharp image on the LCD at that reach. We older folk, might not be that steady - even after changing our glasses.
As for the decisions by many P&S Makers to move away from AAs to the lower power storage "Unobtanium" power-packs - rather strange. As mentioned above, some families in our bunch of friends have several P&S cameras - and with a couple of exceptions, all use AAs and are fed Eneloops.
Partly because several sets of Eneloops for a camera are a lot cheaper than several power-packs - partly because all of 2-3 or more cameras being used on a trip can use the backup charged Eneloops - and partly because if they do run out - the "spare" AA Alkalines (bought in a 16-pack for $11.00) - will also power any of the cameras.
Perhaps the Makers of P&S cameras could copy Pentax's new K-R - it comes with a power-pack, but there's also an adaptor for 4 x AAs. You can buy 3 sets of 4 AAs for less than the price of 1 spare power-pack - and each set will last longer than a power-pack....
