MICROSOFT OPERATING SYSTEMS: 32bit vs 64bit & THIRD PARTY HARDWARE / SOFTWARE

Question

As WINDOWS 7 is the newest, and latest O. S. product from good ole Microsoft, in upcoming weeks and months, lots of people; professional Techs, and regular Users are going to be faced with thousands upon thousands of new obstacles and miscues. Purchasing the 32bit version of WINDOWS 7---or a combo pack of 32/64---is currently the easiest and safest way to go! Still few manufacturers offer their Hardware with Software support for 64bit. Of course, most likely this will be the next wave of the future, but for now, most PCs are operating 32bit Motherboards, components and such.
Performing a CLEAN INSTALL  vs  an UPGRADE is a matter of decisive choice. Though, if you've been having problems with your current Operating System and PC, then chances are, an UPGRADE type of Install is not going to fix your problems. Of course, a CLEAN INSTALL guarantees you will most likely lose previous info and data, but if you back that data up onto a separate Hard Drive, you will be able to retrieve it later (if you don't have two or more Hard Drives installed in your PC, then a stand-a-lone USB type of Hard Drive can be purchased for under a Hundred dollars ($100).
With most of the 32bit Microsoft Windows Operating Systems, technically knowledgeable advanced Users, or Techs while paying exclusive attention during an Install, can direct the Operating System Setup to install without overwriting existing data, however this procedure and process requires a lucid working awareness and understanding on manipulation and navigation of existing Hard Drives.

You don't want those page outs and swap files.
1GB is really meaning that just running web browser, email and something else you will page.
Paging is slower than RAM
Laptops have slower hard drives for the most part still compared to desktops.
I would say 2GB will make a difference even for casual use. Safari alone has been known to use 600MB and up quite easily. Throw in Office, Logic, CS4 and you have a real problem and need that 4GB and up.
64-bit is more about the plumbing and address pointers, registers and can actually take more work to move things around. Your programs would need to be such that they benefit, and that each application or process can benefit from 4GB or more - each. And more than 4GB RAM.
Technical, but the best review of what Snow Leopard can mean for developers and the future of Mac.

The open/save dialogue has been in need of more views for a long long time, and that alone is worth the cost of Default Folder was; Finder has been in need of a rewrite for four yrs finally got it; send windows to its own application in the Dock and not left orphaned on the side and lost.
Multi-core isn't a big issue with dual-core but it has been and would have gotten much worse in the future without SL's Grand Central and other improvements. Moving to new compilers and with the help of Intel to better use new chips and hyper-threading.
Windows 7 runs smoother and faster and showed a lot over Vista and why those that used both won't go back. That is what I would expect to see from 10.6 eventually. There were problems where 10.5.x would get lost, not respond, the mouse would move but no interaction with the system itself, like a run-away train.
