For the following reasons:
- Easy and quick to install,
- Intuitive operation (instructions you do not need the best of intentions)
- Stable,
- Fast,
- Very comfortable (= Windows is integrated, for example in all the normal Apple Bar and is therefore a matter of course part of your Mac)
What I can not say or what you need to know:
- Run freely available programs like perfect?
- The price is justified (or as freeware available, too high)?
In my view, a strong buy recommendation. Windows 7 running smoothly on the new (small) IMac and complemented him for missing functions.
