Hello, I had a question about upgrading to lion. I was so excited to download and install lion on my black macbook (i think it's a late 2007 model). However, when I clicked the buy button, a message popped up saying that lion requires 2gb of memory. I quickly went to my about this mac application to confirm this, and sure enough my computer only packs 1gb of memory. I was terribly disappointed. Apple found a way to basically make me get a new laptop. I haven't really started looking around, but only because I wanted to come here first to get you guys or ladies opinions. Would it be better to just buy extra memory to keep my macbook? Or would I just be better off caving in and getting a new laptop like an Air or macbook pro? Any help would be great!
