Having never owned a laptop, I know nothing about the internal components and the amount upgrades you can do over time?so I was wondering if they are easy to upgrade and what you can upgrade 
?it seems with their size that most of the components are fixed on the mobo, but not quite sure?I see stand alone dimms for sale, so I assume Ram upgrades are easy?I also have seem some laptops being offered with 2 hard drives, so I assume you can add another one depending on the model you get? How about the chip? Graphic card? I am thinking about getting a 700MHZ or so, but hate for it to be totally outdated in a couple years...like to cut costs on a few other things, but would like to upgrade as I get the $$$
