Debian-
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. debian uses the Linux kernel (the core of an operating system), but most of the basic OS tools come from the GNU project; hence the name GNU/Linux. Debian GNU/Linux provides more than a pure OS: it comes with over 25113 packages, precompiled software bundled up in a nice format for easy installation on your machine.
Debian has now decided upon a 2 year release cycle, i.e, a new version of Debian will come out every 2 years.

  • Latest stable Version-5.0.2
  • Kernel- 2.6.26

Ubuntu-
(My OS)
Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more. Its based on the Debian linux.

They issue a new desktop and server release every six months. That means you’ll always have the latest and greatest applications that the open source world has to offer.

(I like this idea of new releases every 6 months, hence i’m sure i have the best)

Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server. With the Long Term Support (LTS) version you get three years support on the desktop, and five years on the server. There is no extra fee for the LTS version, we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.

Hope you find this interesting. I also wanted to brush up my linux updates…
Hey i would suggest you to use Ubuntu and a thing that’ll surely attract you is that-

You can get it for free, right at your doorstep, how’s that???

Just log onto

https://shipit.ubuntu.com

Create an account in it once, and then fill the form with your address and create your launchpad id, after that for every new release of Ubuntu, you can ‘request for a free cd’. Then they’ll ship the ubuntu cd, within 4-6 weeks to your address, and you will get it at your home in a neatly packed cover.
I have got with me all Ubuntu cd’s from version 7.04, till 9.04(i.e,five versions) And hence i have clearly experienced how it has become more useful now. And more stable and useful too.. I suggest that all of you should get your hands on Ubuntu its simply superb. You’ll surely, love it and throw away your Windows… I’m sure. Just try and see… There will be no turning back.

Ubuntu Rocks……….
