Finally the price of 4 GB DDR3 memory sticks are moving in the right direction.
Recently Mushkin announced new 12GB kits (3*4) in their Blackline range (price of which is still not known), and now Crucial is joining by offering 4 GB DDR3 sticks, unbuffered, non ECC at approx. half the price of their Kingston equivalent.
I think others will follow soon with probably even lower prices, so that's good news for those who have been waiting for affordable 4GB DDR3 sticks.
