And yes, time will pass until true 64bits applications are seen extracting juice from our super-multi-stuff-something-64-processors.... Maybe once 128bits processing is around for PC's and alike? And then... a new topic will appear! "128 bits: More than just cookies". Hehehehe

Hi Kross, the RAM which a 64 bit system will support is just so huge that from that aspect I can't see any need to go to 128 bits for a long time. what I will think will drive a migration from 64 bit to 128 bit computing will be home and work place robotics.

The fact that 32-bit systems only have 32-bits of data to work with means that they can only address up to 4 GB of RAM. A 64-bit system on the other hand could theoretically address up to 16 exabytes of RAM (That’s over 16,000,000 GB of RAM). In reality though, there are few, if any, 64-bit systems that support 16 exabytes of RAM. Building a machine that supports that much memory would be extraordinarily expensive. To counter this cost, many manufacturers impose RAM address space limits that fall somewhere between the 4 GB limit of 32-bit machines and the theoretical 16 exabytes that a 64-bit system should be capable of addressing. Most existing 64-bit systems limit physical RAM to somewhere between 8 GB and 256 TB.

Bye the way, what flag is that?
