Looking at laptops

My husband and I went to Best Buy today because he needed a new power supply for his computer. While we were there, I took a look at some of the laptops. I'd really like to get a laptop of my own. One of the biggest factors for me is laptop memory. I need a laptop small enough that it's not heavy and I can use it anywhere but I need enough memory to handle everything I want to do. And, of course, it has to be within my budget. Decisions, decisions!
