In reply to keith-ratcliffe:
I have a Nikon D5000 which replaced my Nikon D50. The only reason I replaced my D50 was because it was beginning to fail with the shutter mechanism. The D5000 has a much more robust shutter count expectation before it dies and till then I have no desire to upgrade just for a few pixels more or for a marketing feature that I do not need.
I would still be using my Nikon D50 to this day had it not started to break. The only real world advantages of my D5000 were superior noise reduction at higher ISO rates and arguably a higher pixel count on the sensor. More pixels doesn't necessarily mean better images.
So unless a new camera had a Killer Feature that I could not live without then I am not getting sucked into the upgrading merry-go-round that is the consumerist's mantra.
My mate is still using his second-hand Nikon D40 and has no intention of upgrading till that too mechanically dies.
I also have a 12 year old Nikon 3Mp compact digital camera which works perfectly fine.
