This is pretty much THE book for info on system internals, kernel coding, etc. It’s rather large and takes a while to get through, but the info is awesome.

Personally I think this article was a little gutsy when the WWDC was going to be the very next week and it was guaranteed that it was going to announce the successor to Leopard: Snow Leopard.  To summarize the competition was close but Snow Leopard was decided as the favored operating system.  The author’s comparison points were interesting and I think it was a fair assessment of the two operating systems. 

However, I thought it was bizarre that they would compare Time Machine to Windows backup.  My first thought was about how I never use windows backup.  I just make a habit to store my important files on a secondary drive and keep the operating system on it’s own drive.  The real backup system is Windows Home Server.  And then a colleague of mine at work pointed out their poll at the bottom of article asks for people to rate the favorite feature about each operating system, and with 10% of the votes Time Machine was the readers favorite feature of Leopard.  Wait, I thought Mac’s were secure and didn’t crash, then why is the backup/rollback system the favored feature? I think I deal more with the taskbar, themes, aero and the file explorer way more than I ever think about my backup.  I am happy it’s there but I tend to go more with the set and forget it method.  But, I guess that is just me.  That’s just my two cents.
