Just bought my first Mac...a black MacBook. I bought it with 1 GB of RAM, but immediately went to Newegg.com and purchased 4 GB of RAM to replace the original 1 GB that came with the system. So far so good. My Dell XPS went on the fritz late last week. It looks like the nVidia video card went to hell and now none of the operating systems will boot up on it. And the Dell is off warranty, so it's going to cost me some money to get the thing fixed. Oh well. So I'm rolling with the MacBook. For Windows, I'm going with VMware Fusion on the MacBook.
