In reply to Mark Stevenson:
manual focusing on a low resolution electronic viewfinder is murder,... or will be when you can't do it and someone walks by.. they are getting better in the latest models but still are just pretty much there to give you a steadier shot whilst keeping peoples head and feet in the shot.
accessories ->
if you're going to do landscapes get a solid tripod (to the max you can afford, theres no point getting a cheap one to replace it once it breaks), remote release, UV filter and polarising filter.
maybe worth getting a cokin adaptor to get graduated filters, tho you'd have to wait for a new lens where the front element doesn't move..
portrait stuff get a decent flashgun (with both bounce and swival)
and you can't go wrong with spare batteries, more cards and other little odds and sods
