Hello Basically, I am using a broken iMac 17 inch (Intel Core 2 Duo) in this moment. It has a broken screen so I have another display connected. It runs Windows XP alone, I cannot install Mac OS because the iMac screen is cracked and there is no way to mirror the Mac OS installation to another display. I got this thing for $200 from eBay and have been using it for almost 2 years. Now Windows XP is full and is terribly slow. Like I said, I cannot reinstall because the iMac screen is broken so I cannot see the installation. I want to buy something else. I do not want Windows so I thought I would go with Apple. I am poor and my budget for a computer is only $600. I would like a laptop or something portable since I am going to college soon. For this money on eBay I found quiet a few 15 inch Powerbook G4s and very few white Macbooks. To be honest, the 13 inch screen is probably a little small for me but it does have Core 2 Duo. Most of these models for the price come with 512MB of Ram so I will have to save more for memory upgrades later. I am really not sure what to pick. There are iMac g5 too around the same price but like I said.. I would like a laptop. Out of these 2 computers which one would last me more? Those Macbooks have good processors but the Powerbooks have bigger screen and Superdrive.. Sorry for my poor English, I only lived in US for little time.
