As I earlier mentioned I'll be ditching my desktop when I move next week, I'm thinking I'll buy a laptop to replace it.  This is not going to be a gaming machine, and I'm on a budget.  Ideally I'd like to spend no more than $750 or so.
Right now I'm leaning toward this one:
http://www.dell.com/content/topics/topic.aspx/us/segments/dhs/catalog?c=us&cs=19&l=en&s=dhsDell E1505 (4th system down starting at $699)  The only thing I'm upgrading is from Vista Basic to Vista pro which brings the tag to $728
A couple questions:  From what I could tell from anandtech the Intel Core 2 Duo was about a 5% increase over the Dual Core model at the same frequency. Dell is charging $100 for a core 2 duo, I'm thinking it isn't worth it.  Also, is 1gb enough ram for Windows Vista?  The recommended specs are 1gb, it would run $150 to up to 2gb, would I be better off upgrading on my own if necessary?  Also, the video card that comes with that model is pretty much shite, but since I won't be using it for gaming I'm thinking it doesn't really matter.
Thoughts?  I haven't even thought about purchasing a pre-built system in forever  Any thoughts or input would be valued.  I'd like to make the purchase sometime soon so I don't have to go long without a computer.
