"Why Linux?"
Answer 2: You can customize the OS at any level. This is possible in great extent because of the source code of the OS available to you. Even a non-geek person like me can customize the look and feel of the OS and also the way it behaves. For instance you can access all possible hardware information and can draw their status on to the desktop. This can be achieved with a simple tool called 'Conky'. There are plenty of customization options available like 3D cube desktop(Compiz) so if you are bored with same look of your desktop you can change it. Surprise for sure!
Answer 3: It's Free. You no need to spend single rupee. All you need is head on to here https://shipit.ubuntu.com/ and order for one CD but it might be take 3 to 4 weeks to reach you. That's fine but I want to spin it right now, dont worry there is a way. Get ISO image from here http://www.ubuntu.com/desktop/get-ubuntu/download and burn to it the CD. Now you can install using this CD and this CD is called Live CD in Ubuntu world. Simple isn't it?
Fine Let's move to other direction where Ubuntu Linux shortened it's ability. The first thing is the absent of popular applications like Photoshop, Flash Authoring Tool and almost of all Microsoft Applications. So if you are a die-hard fan for MS applications then this is not for you. Still there is a way to run a windows applications in Ubuntu Linux through a tool called 'WINE'. Most importantly their is an alternative software for all windows software. Check this website http://www.linuxalt.com. The second thing is lack of hardware drivers for your hardware say like Printer or Modem. Nowadays this is not a big issue since there is a workaround solution/alternative options for your issue with just a click of Google search/Ubuntu forums.
But I am sure these are the common pit-falls for long time. Nowadays things are changing rapidly and with new kernel version and more OEM(Original Equipment Manufacturer) partnership these pit-falls surely will be a past story.
Let's spin Ubuntu Linux OS.
