I would guess so, since linux is a lighter OS and doesnt have crap running in the background.
Do you have any evidence to support this claim though?
Standard fresh install of XP Pro is ~2GB
Fresh install of a xfce can be within 500 MB
But if you need evidence then you obviously haven't used linux / unix that much to actually know.
A live cd of xbuntu is 600 MB, that is the full os being able to run, yes packages are in a compressed environment, but you can't stick a full install of XP on a cd and expect it to run.
If you truly want to learn about linux, go back to the early days. I remember sitting at my desk having to recompile my kernel because I needed to add a driver for something, and a gui, you had to install that yourself.
An OS that uses linux is Ubuntu, and Ubuntu also seems to have the advantage of encrypting disk space to make things safer.
And honestly the whole intention behind the OS seems to be based off an intention of compassion and virtue and sharing,
just looking up the definition of the word ubuntu may show that.
Ubuntu is a flavor of Debian. All they did was take Debian and spice it up and make it look pretty.
Now if you want to stick to roots and go with something nice, but not a flavor of another distro, go with Fedora Core. Fedora started as Red Hat, then Red Hat became the enterprise distro and Fedora Core became the public distro.
I using XP, it is best Windows ever, especially on low end computers.
Have you heard of the windows pattern? http://www.urbandictionary.com/define.php?term=Windows%20Pattern
That pattern has held true to the Windows 3 days, god I miss my Windows 3.1 machine, I must be getting old.
Me personally, I love Red Hat / Fedora Core but people who are releasing programs are sticking to debian distros. Yes you can repackage the .deb's to .rpm's but sometimes it is easier to just go with the flow.
