This is from a guy who left Google to return to Microsoft:

The culture part is very important here - you can spend more time fixing bugs, you can introduce processes to improve things, but it is very, very hard to change the culture. And the culture at Google values "coolness" tremendously, and the quality of service not as much. At least in the places where I worked.

Since I've been an infrastructure person for most of my life, I value reliability far, far more than "coolness", so I could never really learn to love the technical work I was doing at Google.

I'll keep that in mind the next time I have to reboot Windows. I can still count the number of times I've rebooted my Mac (other than for system updates) on one hand, and I've had it for a year now.

Update: As if on cue, my old Windows (XP) laptop just froze up on my daughter - screen turned black, and all we could do was power cycle it.
