A PC user for quite a long time, I'm somehow switching to Mac. "Somehow" because circumstances make that: 1st I will continue using PCs quite often and 2nd I'm entering Mac with a rather old model. And this is where your contribution is needed: Hopefully, I will soon have an iBook G4 12" (a real portable laptop, not like the one I'm using right now, which kills my back when carrying it!). I'm getting it second hand and, as a first time Mac user, I obviously have a few doubts on which model to get. I've been doing my research and come to the conclusion that it is the G4 that I want (read rather: I can afford...). The thing is, which processor speed? Here is where I have the doubts I haven't been able to solve. Those of you who have or had a G4, would you say that an 800 MHz processor would be ok or should I expend the extra money and go for a 1,07 GHz or 1,33 Ghz? As far as photography is concerned, I'm going to be using it to BASIC edition of 10 MP RAW images. The software, probably Nikon view 5.1, Nikon capture 3.0, and/or perhaps Photoshop Elements (version?). Outside photography, no other uses worry me, unless the iBook would have problems playing DVDs or movies (.avi extensions and the like), which I will be doing as well. I don't need the Mac to be really fast; I just don't want to have to wait minutes before having a picture saved to JPG from its RAW original. The price difference between under and over 1 GHz is considerable, and my worries are that I might not notice the difference having expent the extra money, or the other way round, save money but have a significantly slower machine. I don't mention RAM because that one is easily upgraded. Either way, I would try to go for at least 640 MB, 1 GB preferably. Oh! If that matters, it will likely run Tiger, maybe Leopard. Thanks for your patience and for your contributions! they are much appreciated!
