It looks obvious

I’m used for OS upgrade and pretty much loath them. I can’t recall even one Windows upgrade that went well, at the end I always needed to format the hard drive and install the new version of Windows on clean system. It is also took several months until everything that use to work in the previous version was fixed and worked again. Not for nothing it is common habit among Microsoft’s user to wait with new software until the first service pack is released and make the software usable. 

So it was no wonder that, despite the great reviews and the general enthusiasm, I took a cautious approach when I prepared to upgrade to OS X Leopard. Although, cautious or not, I’m an early adopter by nature and I rushed to upgrade on the release date. Before upgrading I backed up my entire hard drive and made a complete list of my applications and setting - ready for the unavoidable formatting and reinstalling as I’m used too.

Several hours of preparations and all for nothing! I started the installation, went to upstairs to get a cup of coffee and when I went back it was all done. And it was the cleanest installation I ever experienced. Since I was skeptic I performed a careful and extensive checking of the system and my applications and every thing is working perfectly. Even more surprisingly Leopard is all what the reviews promised. Unbelievable!
