I know, I know, wait and see what it looks like, and I will. But...I was just wondering what the noticable speed differences would be between a G4 1.33 and a G5 1.8. A new computer is going to be coming to my house soon, but I still am having problems deciding. I would like something that will last me atleast 3 to 4 years and I will mainly be using it for internet, iMovie, iDVD, Photoshop, Office, iTunes, and a few games like nascar or Sim City (I'm not a huge gamer I just like some fun every now and then). Do you think that the G4 wouldn't last as long as I would like? Would I notice huge speed differences? I know the 12 in. Powerbooks aren't 64 bit or whatever, but will it still work smoothly with Tiger? What else should I think about.
