Hmmm - what exactly is the need for "64 bit" for desktop machines?

BTW your old computer is no good because it doesn't have the new metallic blue racing stripes. I think you should spend $2000 on hardware and another $1500 on software, just so you can take advantage of these nice new racing stripes. To ensure that your wallet is emptied sooner, we'll be discontinuing support for the old "non-striped" models, because honestly, all computers will have fancy blue racing stripes by the time we've convinced suckers that they're useful. Send your check for $3500 today (or 40 easy credit card payments of $100 a month) and we'll throw in a set of free steak knives! But ring quick - stocks are limited..

While the 64-bitness of AMD and Intel's new chips isn't useful yet, these chips are greatly beneficial for a couple of reasons. First, the extra registers that come with the x86-64 mode provides flexibility and performance. Second, DEP makes it easier to write secure software.

Now that I think of it, 5 - 10 years from now, 3GB of ram on a desktop machine will be fairly common. It's a good idea to start building up demand now, so the industry is completely ready once we start feeling the pinch.

Not much today. But in order to implement 64 bit we need hardware, an OS, and applications. The latter two aren't going to happen without the first two.
So my answer is that we don't need it today, but if the next ten years are anything like the last ten years--then we surely will need it. And it is a long implementation cycle.
Vista's successor (Windows 2020? We see clearly now?) will be MS's first 64 bit only OS.

There are two main reasons to use 64 bit machines, both are likely to need the ability to use the much larger virtual address space.

1. For handling very large databases.
2. For video editing.

The first reason is why Opterons and 64bit Xeons are going out the door fast primarily to run Oracle, DB2 etc. The second case is as far as I know the only reason why you would need a 64 bit desktop machine.
