Is there anything wrong with getting 2GB of RAM extra put on my computer? (please share your advice)?

You talking about the laptop? Well, first off adding ram will make it run fast for sure. Now, you have to find out if you have Vista 63 or 32 bit. If you have 32 bit, no use getting 4 gigs since your laptop will only read at the most 3 to 3.5. Also, it depends on how much your motherboard can hold too. A few things to look into before adding.
