Consider these memory requirements for Fedora Core 2, as specified by Red Hat:
Minimum for graphical: 192MB and
Recommended for graphical: 256MB Does that sound any alarm bells with you? 192MB minimum? I've been running Linux for five years (and am a huge supporter), and have plenty of experience with Windows, Mac OS X and others. And those numbers are shocking -- severely so. No other general-purpose OS in existence has such high requirements. Linux is
getting very fat.
I agree 256MB is realistic
Have a look on any major PC manufacturer's website. Until recently (I haven't looked in a while but maybe even still now) most laptops and pcs were coming with 256MB RAM as standard. Tho in my experience having a standard set of apps (Office suite, mail program and a browser) on that setup will begin to swap like hell on Windows after a couple of weeks of daily use.
Linux it seems will stay at the same level of performance without degrading over time at least but XP on 256 to begin with it fine.
