I'm in a market for a laptop & today I came across two ways for configuring my soon-to-be-new computer. Building your own: Dell & Gateway makes them. Customizing what software, RAM, OS, Processor, etc. would seem like a good idea. I went to the Dell Kiosk @ the mall to "play around" what I want. Pre-built: All other manufacturers, but way too many choices. What seems more appropriate among these two options for a laptop? I'm planning to buy my laptop before Christmas.
