Microsoft will soon no longer support Windows XP so current XP users will need to migrate to a newer version of Windows or possibly Linux. If they don't migrate, they run the risk of serious security problems once Microsoft stops issuing updates for Windows XP.
Softpedia examines the possibility of upgrading to Ubuntu 14.04 LTS for Windows XP users.
A lot of Windows XP users are looking to make a change after their operating system will cease to receive security updates from Microsoft, in April. Like most people who are migrating to Linux, they have a lot of questions about various aspects, regarding its use and its capabilities. The truth is that probably Windows XP users are more scared than they should be, as we will show right now.More at Softpedia
One of the issues with Windows XP computers is that many of them aren't exactly top of the line. Trying to run Windows 7 or Windows 8 on such older machines might not be a very good idea. Such computers can be too slow and lack the resources necessary to provide good performance on newer versions of Windows.
Ubuntu, and other Linux distros, can run pretty well on older hardware. So I think it's a great idea for Windows XP users (companies and individuals alike) to seriously consider Linux. But it also makes sense to take your time to find the right Linux distribution to use as a replacement.
While Ubuntu itself is a fine distribution, there are plenty of other options for those who prefer to steer clear of it. Ubuntu also isn't generally considered to be a lightweight distribution, so if you are running Windows XP on an older machine with limited resources then Ubuntu might not be your best bet.
Here's a brief list of lightweight distributions, courtesy of Wikipedia.

Peppermint Linux OS
Tiny Core Linux

If I had to pick a distro or two off the list I'd probably go with CrunchBang, Bodhi, Peppermint or Lubuntu. But the other options might work well for Windows XP users as well. It's really just a matter of trying out some distros and choosing the one that works best for you in place of Windows XP.
XFCE better than GNOME and KDE?
Datamation thinks that XFCE is better than GNOME or KDE.
Over the years, I've spent the bulk of my time with the Linux desktop using either GNOME or KDE. Both environments have grown over the years and each desktop has continued to expand its current user base.
The sleeper desktop environment – which I didn’t even considered years ago – has been XFCE. I've found that XFCE offers more robustness than say, LXDE, which lacks much of XFCE's polish in its default configuration. XFCE provides all the benefits one may have enjoyed in GNOME 2, but with a lightweight experience that makes it a hit on older computers.More at Datamation
