1. Mac OS X
1.1. Pros
1.1.1. A dedicated app for browsing and buying games
1.1.2. dedicated app for browsing and buying games
1.2. Cons
1.2.1. The only problem I am having is the Boot-up it is slow in booting up as compared to Snow Leopard.
1.2.2. Autosave is a nightmare in real life
2. Ubuntu
2.1. Pros
2.1.1. ‘open-source’ means that you can access and alter the source-code of an application, allowing you to add your own functionality or improve the performance of the software
2.1.2. Ubuntu is completely free to use. There is no trial version, no license key to worry about and definitely no activation of any sort.
2.2. Cons
2.2.1. after the installation of some programs, it sometimes can be difficult locating and starting the program
2.2.2. The community can be incredibly helpful at times, but sometimes they'll be unfriendly, and I mean HUMAN unfriendly (I came across someone telling me RTFM (Read The F*cking Manual) before)
3. Windows
3.1. Pros
3.1.1. Standard with windows 7, get more with your digital media with Windows Media Center.
3.1.2. Windows 7 groups everything you are looking for in the Action Center. Now, you don’t have to hunt around for a setting you don’t often change.
3.2. Cons
3.2.1. Some of your old software just will not work in Windows 7 regardless of whether you choose the 32-bit or 64-bit version.
3.2.2. When you upgrade to Windows 7, you have to decide whether to get the 32-bit or 64-bit variety. Confused? So are a lot of people. Look into this one carefully because once you install one or the other, you can’t change your mind without a full reinstall.
