Apple Imac G4

I have been to the Learning Resource Centre (LRC) many times but I did not know there are Imac's. Today, my class ended earlier, so I decided to explore the huge LRC. It was nothing special until I reached the 3rd floor where I seldom go, I am a lazy boy. I was so excited when I saw Mac's around. I was thinking to buy a Mac as I do not have a workstation currently. I have sleepless nights, thinking of my ability to handle a Mac, how does MacOS looks like. After the try, I got more interested to own a Mac. Before I was planning to buy an I-Book, when I saw Imac, I was attracted to it! I browsed to Apple's site and compare the prices between I-Book and Imac, the price difference is not much but the performance varies a lot. Still doubting which one to buy. Nevermind, I still have time to consider as my bank account is not ready to be used yet.
