Link: Magic Number: 30 Billion.
Sure this is mostly back of the envelope calculation but I can believe it is close to that number. I've never had a windows box that I haven't had to reboot daily to make work better.
No wonder I feel more productive on my Mac. I really am. A computer will usually crash at the most inopportune time, during flow time, and after all the restarting and getting back to where you were, 10 minutes to reboot and get all the applications and documents open again to where you were, 15 minutes to get back into flow and hopefully not get distracted by email or the web.
You've lost half an hour just to get back to where you were. With these kinds of losses even just once a day much less twice, you are having to run just to stay in place. The computer previous to my current PC was so bad I rebooted at lunch and turned it off at night to reduce the number of crashes to a manageable amount.
My current PC is pretty good but if often needs a reboot to see the network, though now it does only that. It completely ignores the Ethernet network for some reason though it shows the cable as connected, and can see the other computers it just doesn't connect for anything more.
What a waste.
