I had similar thoughts..
The poster above saying that; 1GB should be find for a small web server and such, or the article a few days back complaining that a phone "only had 512MB" to run in.
At the other extreme I clearly remember using VAX/VMS at work with as little as 20MB Ram and tiny hard disks, that supported:
- 10-20 concurrent software developers editing, compiling and testing code (via dumb terminals).
- a decent file system, with native indexed files, version numbers and more.
- a built in mail client.
- the equivalent of MSN (called Phone)
- printer server
- Word processing (WordPerfect was available for VMS)
- File serving via FTP and DECnet
- and much, much more.
I acquired a couple of VAX's a few years back and I gave one to a friend who has used it the run his personal web site for nearly 10 years.
It has never been hacked (though the logs show the script kiddies were trying within 40 minutes), and the only down time has been due to him moving house and a few power failures.
Not bad for a microVAX 3100-95 (~38VUPS or the speed of a 100Mhz Pentium) with the maximum 256MB and a GB or so of hard disk.
