Hi
What is the difference between the 32 bit and 64 bit? Context: "Absolute Beginner" running a stand alone home PC to pick up email, skype, and a little spreadsheet and document stuff and occasional surfing

- 64 bit allows you to address more RAM, 32 bit is limited to less than 4 Gigabytes whereas 64 bit practically has no limit.

- In 64 bit Systems processing of calculations at higher precisions should be faster.

So in practice if do not do intensive numeric calculations (including video encoding) often and you have less than 4 GB of RAM you might as well stick with the 32 bit.

why use 32 bit if your system is capable of 64?

64 bit will have lot of space for addressing. so you can atore large data as well as speed of accessing will be high.
you can read more here (http://en.wikipedia.org/wiki/64_bit)

Because some hardware (like mine usb wlan stick) does not support 64-bit yet :p.

Actually, that's not true. Any 32-bit Linux kernel that's been built with high memory support can address 4GB per process, up to a max of 64GB.

64-bit is faster (particularly at some tasks), and is what all new chips are built for. 32-bit is the old standard. I can personally vouch for 64-bit being smooth sailing on Linux, so i'd say you've got no real reason to throttle your chip down to 32-bit.
