XP runs fine on a 500 MHz Athlon with 160 MB RAM. Just don’t expect to do much more than email and Web, and you have to turn off the eye candy.

That's not what I consider running fine, at least for business. Running fine for work is the ability to run Outlook, a CRM/CRS program, a browser for Sharepoint, a browser for another activity, and Word or Excel.

Of course some people have greater needs. I multitask and tend to use as many resources as possible. I am currently running: Outlook 2003
ACT
Quickbooks
A proprietary database using Visual Basic and SQL, in which I am running a report.
2 instances of Firefox , one for FR and one for private email.
I really like having 4 GB of RAM and my Core Quad Q9400. I don't know how I worked before I had 2 monitors.
