I've been in a local retailer today having a play with some IMac desktops and I am very impressed. Aside from the operating system which does seem to be a lot less complex and a lot quicker, I was very impressed with the quality and clarity of the screens. I also liked the IPhoto software package. Getting quite drawn into Macs but don't know whether Imac or Macbook is the way forward. I do think the 24" screen would be handy for photo work though....
