Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have 6 systems in my home four of which are 64 and two are 32 bit.
I still tend to run 32 bit versions of distros simply for the stability and compatibility they still have over their 64 bit versions. I do run several 64 bit distros for testing and haven't seen much of a performance increase when compared to their 32 bit versions, additionally in many distros recompiling the software in the repos to 64 bit is lagging behind, so while most of the software the devs feel is most important has been ported over, some you feel is crucial may not be, and may not be anytime soon.
I'm sure in a year or two I'll switch over but at the moment it seems the benefit of the 64 bit versions are generally outweighed by the drawbacks.
I had to check the date of this post to make sure it wasn't from 2003. I haven't noticed any of the problems you describe with 64-bit Linux in over a decade...
Wow 64 bit Linux distros is 2003. What distro was 64 bit in 2003 and what hardware did you run it on?
Sorry was a year off.
AMD released the 64-bit opteron in 2003, Intel released the 64-bit Xeon and P4 in 2004. Linux has supported x86_64 since 2001, with many distros adopting it in 2003. I've been running 64-bit Linux on a daily basis since 2005 and haven't noticed any of the issues you've mentioned in a LONG time. In fact, that 64-bit machine from 2005 that I mentioned above is still running to this day, 24/7.

I bought an Athlon 64 within 3 months of them being released (so like Jan 04), and started using 64-bit distro shortly thereafter. Although it was 2 years or so before I made the switch permanently due to lack of many programs being avaialble, but I can't remember having issues with anything major missing since 06 or so.
I voted "x86_64", but I might not be eligible to vote, since I only downloaded and tried it today (Mint Linux 15, and it worked no problem, I downloaded the .ISO file, used a Windows program called "Universal-USB-Installer-220.127.116.11.exe" to transfer it to an SD card, and by changing the Boot Order in the BIOS of my laptop, managed to boot straight away into the Linux installation on the card.
I'm new to Linux, so I can't really judge Mint Linux, but for a total beginner it boots flawlessly, and doesn't ask any (seemingly cryptic) technical questions before it gets to the desktop.
Well, welcome to Linux & the LQ community J.Doran! Mint's a great distro to start with
