Dunno.

EDIT: apparently silver is fairly unreactive too: http://www.docbrown.info/page03/Reactivity.htm#silver
Maybe there's some other reason, such as costs to meld silver??  Seems unlikely though.

Well i looked up the melting points of the two metals and silver is lower
(silver= 1763.20 °F,
gold= 1947.9741 °F)

So its not that either...

however, after reading a little more on the link you posted, i found this

Quote:Of the metals commonly used for conductors, copper has a high conductivity. Silver is more conductive, but due to cost it is not practical in most cases. However, it is used in specialized equipment, such as satellites, and as a thin plating to mitigate skin effect losses at high frequencies. Because of its ease of connection by soldering or clamping, copper is still the most common choice for most light-gauge wires.

I think this webpage is  extremely outdated, or has been tampered with, hoping for the best, im going to do a little more research...

OK, after thoroughly reading through that wiki, i stumbled upon this,

Quote:Because it does not corrode, gold is used for high-quality surface-to-surface contacts.

so according to wikipedia, gold is used so that the computer lasts longer.

EDIT: because i wasn't satisfied, i did MORE research that proves my theory
as said here:

Quote:It's an issue of corrosion.
Gold contacts maintain a better connection, longer.

Like Tom posted.....a search will bring up the reasons why.

found on this forum asking the exact same question wee have been pondering
