I don't get it. The iPad does not turn on instantaneously from being turned off. It does turn on instantaneously from sleep, as does my MacBook Pro (aside from some significant caveats, such as the time it takes to re-join a wireless network). The trick with the iPad is that sleep is the state you get when pressing the button that looks suspiciously like a power button. The iPad also does not have a Safe Sleep or Hibernate state like the MacBook does, so it will drain battery until turning itself completely off. Is the solution to design a laptop that you never turn completely off except in rare circumstances?

The solution is to enforce the same "save everything, all the time, because someone might hit Home on that shit at any moment" philosophy that gets rid of the difference between close, quit, sleep, hibernate, and power-off for iPhone and iPad apps.

  An alternate solution could be a timer that switches the MacBook from "ram-sleep" to "disk-sleep" automatically after 10 minutes or so. Currently, when you close the lid, it will just ram-sleep until the battery is almost dry and only then suspend to disk. It's quite frustrating to pull the MacBook out of its sleeve in a meeting only to realize it has "slept itself to death" once again...

    You might want to check up on that: does your MacBook keep playing music if it's "ram-sleeping"? If so, it might not really sleeping as hard as it should. I've kept my MBP's in "I shut it and put it away" mode for days without noticeably losing juice.

Yes, but laptop batteries do not last anywhere near long enough to make this feasible, and the faster the wake time the more power required to stand by. To get instant response with the memory footprint of a laptop, you absolutely MUST keep the RAM powered or else radically modify the existing technology in ways that haven't been thought of yet, and Apple is not in the inventing-new-hardware business (rather, the apply-existing-hardware-to-new-ideas business) In other words, it's what we'd like to have, but with current technology it is an unworkable solution (as it would require either massive batteries, slow CPU's or constantly being plugged in)

  “Yes, but laptop batteries do not last anywhere near long enough to make this feasible …” Uhm, I never turn my MBP off, I always just close the lid. I’m not seeing any diminished battery life. My 2007 MBP already behaves pretty much like an iPod touch or an iPad. It’s mostly an UI problem, not a Hardware problem.
