First, I rarely reboot my MacBook Pro; I just put the machine to sleep and wake it (and this is easily accomplished by closing and opening the lid).
Second, I rarely reboot my phone; it also seems to sleep1.
Third, the context driving this War on Boot Times is our increasing dependence on external information sources. Think back to 19882 and you may recall a time when finding out what movies to see while you were away from a newspaper was a non-trivial task. Now with a smart phone or a WiFi connected laptop, all the information to answer your question is readily available at a moment’s notice. Think back to when you were out and would say: ‘I wish I could Google that’; now you just do it no matter where you are.
The PC makers are fighting the last war. This whole concept of reducing boot times is irrelevant. The device should already be on and waiting on us. No wait, make that The Cloud is already waiting on us.
The trend is for more information, delivered faster, and requested instantaneously. Someone should tell the PC makers.
1 I am unsure exactly what the phone is doing when it is asleep.
2 Moviefone was created in 1989.
