The answer is obviously, "yes", but the question is when. I am ultimately looking for a better interface and more seemless integration of my digital lifestyle. I know that the mac and OS X will provide me such with the suite of ILife apps. However, I am currently running Windows XP on my Vaio desktop that has the Intel 815 chipset which is a P3 867mghz with 512k of ram. I am quite content with the performance with regards to everyday usage, email, websurfing, digital photos, etc. What I am craving is Imovie and Idvd and the integration of those with Itunes and iphoto along with the elegant design of the Mac. I am indifferent whether I buy a desktop solution or a portable solution as I will eventually get both. What I am concerned about is that I do not want to buy an Imac now and not have a pick-up in experience outside of the Ilife apps. I am very sensitive to the limitations on the front side bus of the current genration of processors. That said, the G4 with level 3 cache would meet my needs, even though I am only a consumer/home user. Should I, 1) buy the 15" when it is released and wait on a desktop replacement when the IBM 970 occurs, or 2) Buy an Imac ( which gives me a faster hard drive and Dvd burner, but no Level 3 ) and wait to purchase an upgraded Ibook. Thanks for the feedback.
