Laptop upgrades

I was thinking, since I don't have to buy a new light for my bike for $50 that I might look to see how much a new laptop hard drive would be for my old Dell Inspiron 1100 and what do you know? they cost $50 for 160gb.  I also found 1GB ram for only $30.  I'm seriously thinking about getting the hard drive but then wait until next month for the memory.  I really want to upgrade my laptop because it's soooooo slow and it never has any space for anything.  It's only a 20GB hard drive and with windows installed and nothing else there is only 8GB available for programs and some of the programs I have take up a lot of space.  I'd also like to install EQ on there and I can't because there is no space for it and with only 256mb of ram it's not fast enough for EQ.
