On the Dells I was looking at 500GB was standard and included in the price. :dunno 4GB was the standard for memory. What's the difference between 4 and 8 GB? Speed?
Which Dell did you get? I kinda like the Studio 17's.
I have an Inspiron.
Pretty sure when building at Dell you can downscale some specs and it reduces the price.
Here's the best analogy I can give for explaining memory and HD space and why memory is probably the most important thing you can have:
Imagine a huge library with millions of books. You're sitting at a single table in the middle. The million books are your hard drive. Your table is memory. There's only so many books you can have on the table at once. If you fill up the table, you have to walk some books back to where they go before you can get more off the shelf. It is a lot of wasted time and effort to be walking around carrying books instead of at the table reading. If you had a bigger table, you can have all the books you need at one time without ever having to get up from your chair, return some books, and look for others. That's why you want maximum memory on any computer. All of the info you could possible want is instantly "at your table" without having to move info back and forth from your hard drive.
Make sense?
