I'm thinking of buying a Fujipix S5600, are there any other digital
cameras around this price and ability that I might also consider?

The things that specifically attract me to the S5600 when compared
with other similar cameras are:-

   It uses standard AA batteries and I'm well stocked up with those
   and have nice portable chargers for them that can be used in car
   on 12v as well as the mains.

   It's pretty light compared with some of the competition and the
   reviews I have read say it's comfortable/easy to use.

The minor downsides are:-

   It's only 5.1 megapixels but I suspect that for what I want this
   will be quite adequate, I'm not aiming to try and take pictures
   for printing huge enlargements.

   The wide angle end of the lens is only 38mm equivalent, I used to
   find 28mm on my OM-2 was a bit limiting, 38mm really isn't very
   wide at all.  However there are few alternatives that I can see,
   there are some cameras which manage 28mm equivalent but they
   mostly have other more significant disadvantages.

Are there any other cameras I might consider in the same sort of price
area?  The S5600 can be had for a bit less than GBP150 but I'd consider
up to GBP200 or so for something that offered more of what I want. I'm
not necessarily fixed on the 'super zoom, pseudo-SLR' format but it
seems to offer more of what I want at a given price level.  I might
consider a good 'compact' as weight and portability is a significant
consideration.  I do specifically want:-
   Fast shutter response
   Uses AA rechargeables
   Viewfinder of some sort (i.e. not just screen)
   Some wide-angle[ish] ability
