Why then should someone prefer 64bit over 32bit?
4 Reasons:
1: Date/Time stamp, Unix time doesn't work in 32-bit past 2038 (not
really affecting us much, most of us will replace our PCs long before then)
I believe even 32-bit kernels now keep the time in a 64-bit integer. This shouldn't
apply any more.
2: Access more than 4GB of RAM (definitely becoming increasingly
important)
The 4GB limit is only on processes. Most recent 32-bit Intels can address 32GB of system
memory. Not necessarily relevant, but a win for Linux (Microsoft never figured out how to
make this work :).
