Faster... Double RAM... Same Price...' Yes I did not pay extra also, I will be uploading images soon, as I'm in the office right now! I dont know if this is a joke or not, maybe you guys will be able to help

Probably not a joke -- I recently heard that populating RasPis with 512MB RAMs was up to the distributors. If they can sell 512MB RasPis for US$35, they can go right ahead and do so. At some point larger RAMs become as cheap as smaller RAMs, and the smaller ones actually get more expensive as chip makers switch over to the larger ones. Over the long run, RAM chips never get cheaper -- they just get bigger for the same price, just like disk drives.

Can you find the RAM chip part number? It's the large square labeled IC2. (The BCM2835 is under the RAM chip.) For example, my rev 1 RasPi is a Samsung K4P2G324ED, where "2G32" = 2 Gbit (256MB), 32-bits wide. You may need a magnifier to read the number.

I wonder how much faster Midori and other browsers will be with 512MB. My understanding of GNU/Linux is that it tries to keep disk files and directories in RAM and only spills them out to mass storage (e.g., SD card) when it needs those RAM pages for something else. If the browser and Internet cache fit into RAM, there's little need for SD card access and a major bottleneck should go away.
