Use WineHQ to run Windows Applications

If you are using Ubuntu and you want to run an application which is not available on Ubuntu, you can use WineHQ to run Windows applications. Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OSX, & BSD.

Use Virtual Box to run Windows within Ubuntu

If you want to run alternative operating systems within Ubuntu (such as Windows or Solaris) you can use Virtual Box. After the set-up of virtual box and the configuration of operating systems, you can run their applications too (alternative to WineHQ).

Optimally you buy recommended hardware components that work on the spot.

The migration from Windows to Ubuntu is not very difficult, but also not very easy. It's like moving house, everything feels a little out of place for a while. For a smooth migration I suggest the following: 1. Install Ubuntu first as dual boot beside your Windows installation or 2. Start with Ubuntu 12.04 LTS.
