I have decision to make. My 6 yr. old G5 is being euthanized. Don't feel bad it had a good life. Anyway I'm a photographer/graphic artist and use CS4 extensively on the G5. However with a new system I'll be going to CS5 and I am between the Macbook pro 2.5ghz with turbo boost or an equivalent priced iMac 3.4ghz. I like the speed of the iMac and from my research it seem to out perform the Macbook but the portability is also important. I'm just not sure that incremental performance is worth giving up portability. I'm looking for some real world experience with CS5 on either of these two platforms. Any help/suggestions are appreciated.
