Dell has better customer service and support for their laptops.... or their computers in general
If you can fix things yourself on a desktop an HP is usually good too, but IMO not quite as good as dell.
Dell computers in generally are usually easier to restore to operation after a HDD crashes
I would not even consider depending entirely on a laptop for anything important.
My personal motto about computers is that a computer with only one Hard drive is a
device designed to LOSE all your data.
Write this down: There are two kinds of Computer hard drives those that have
crashed and those that WILL crash. when they go they take everything stored
on them to whatever afterlife machines get...
Laptops get lost or stolen too...
Frankly rather than buying ONE $1500 laptop I'd get two $750 laptops and whatever drive they came with I'd replace the HDD with something larger made by Western Digital rather than the typical lowest bidder crap most laptops come with
(Typically Hitachi, Fujitsu or Samsung)
"portable drives" like USB drives are fine... if you NEVER carry them anywhere
because they only need to be dropped ONCE to become nothing more than a
paperweight.
Unless you can afford the newer solid state drives
I think an SSD inside a USB enclosure would be the perfect thing for data preservation, but at a minimum cost of ~$1.50/Gb of storage space... (compared to conventional Hard disc drives at ~$0.10-$0.20/gb)
You need a laptop AND a desktop, the desktop needs atleast three hard drives
one of which will be purely dedicated to "synchronizing" everything you have
on the laptop to it. and the other two set up more or less as duplicates to preserve the setup of the computer, your actual schoolwork data and your applications.
If you want entertainment you'll need even more space, but if you lose all your
mp3's or a seasons worth of your favorite TV show it isn't a big deal, annoying, but
not a disaster.

You only need to lose ONE term paper to forever be willing to justify the cost of planning backups BEFORE you lose everything.
