Question: I have decided to switch from Window to Linux.
Should I use Ubuntu or Kubuntu?
Or there are other handy alternatives?
I'm a LAMP based developer.
Any help would be appreciated.

Answer: 
I've always used GNOME (Ubuntu), but KDE (Kubuntu) looks really tempting right now.

It's entirely possible to have both on the same system, and I do. 

To do so, in the terminal in Ubuntu, type this:

```
sudo apt-get install kubuntu-desktop
```

After you do that, right before you log in, the bar at the bottom of your screen will have the option of going into GNOME or KDE, and you can change every time you log in.
I think both have a live cd, try them out and figure out which one you like better. There are tons and tons of choices, which one works for you will be 100% up to you. Basically you are asking about gnome vs kde, which is a basically a religious war :)
