I don't agree with the analysts on this one. Half the analysts are always wrong anyway (ie stock picks and market direction) so just because some analysts said PC prices will go up doesn't mean anything to me. If the economy is still recovering, sales of PCs or components will obviously not be tearing up the charts so to speak so it doesn't make sense to me that someone can say "Oh no one's buying, so let's raise prices." or "Oh, more people are jobless so let's raise prices."
Okay, memory prices are rising but that seems more like a normal bounce from the way they fell in price last year. Their prices might peak in a few months and then they'll level off or even come back down when manufacturers ramp up production but I don't believe memory can continue to climb up. Consumers expect to pay $60-$75 for 4 Gigs RAM and anything higher, people will just wait to upgrade.
Analysts could just be wanting to drive up sales, trying to get people to buy now "before the prices go up".
