Hello, I have never owned a mac before, so I would like some advice. I currently have a Windows laptop, but I will probably be building a desktop PC during the holidays. I was browsing eBay to find out the price of Macbooks, and I saw a listing that caught my eye. Here it is: http://www.ebay.com/itm/Apple-MacBo...129&pid=100015&prg=1006&rk=1&sd=350614256500& Assuming that the laptop is in pretty good condition (He does list some small problems), is it a good deal? I was thinking of selling my laptop to buy it, seeing as I would be getting another Windows machine later. My current specs are: Intel Core i3 (Sandy Bridge): 2.2ghz 4gb RAM 500gb 5400RPM HDD Intel HD Graphics 3000 Around 15 inch Screen (15.6"?) As far as I can tell, the processor would be slower and the graphics would be about the same. I could upgrade the HDD and RAM with some extra money. I am not sure about which machine I would rather have. I am pretty good at keeping Windows maintained, but I still have some problems every now and then. Would the Macbook be much slower when I upgrade the RAM and HDD?
