currently have the new iMac w/ 2 GB ram... how much do you think prices will drop after a few months - 1 yr? right now i think i saw 4 GB of crucial RAM at newegg for $80 http://www.newegg.com/Product/Product.aspx?Item=N82E16820148159&Tpk=200-pin+SODIMM%2c+DDR2+PC2-6400 anyone seen any better deals at reliable places for reliable brands? and will moving up to 4 GB significantly improve normal day to day uses such as time opening programs, etc. ? or where will I see the most improvement when going up to 4 GB?
