I don't think I can be more specific without violating Texrat's sensible suggestion that we stop personal-attacking in this thread that has another sensible topic. However, I think you know that I don't think you are a particularly adroit diplomat.

Thanks. I was just surprised and confused because your reply directly followed mine (which asked for civility), and linked people asking for civility with making personal attacks...

you may laugh, but that's been done.

Something that Sony was showcasing a couple of years ago is a bit on that line, although more radical: create a pre-initialised image to load at boot, just like if the device was doing a restore after a suspend-to-disk.

This works well for something like a camera where the set of apps to have running when powering on is well known and limited.

However there could be some hybrid implementation where the basic system is saved in the image and a list of running apps is saved before switching off.

But i still stand for my point that one should _very_seldom_ have to reboot/power_on.

I don't understand. If I leave my house I want to take my NIT with me. Do you follow? Now, I also want my NIT full-powered so I can use it as long as possible. Got it? I assume this is a common usage. Now, how does one achieve this? Lets assume the user plugs the power in the NIT at evening to charge it. Before she goes to bed she unplugs it. The NIT is at full capacity. Next morning, you take it with you, unpowered. At the moment you start using it on your travel you want to boot it. Do you want to wait 1 minute then? No. You want to have it on as quick as possible. Do you want to have the boot process using a lot of power? No. You want to have it use as little as possible. However, fact is, in these situations you boot your NIT every day you use it.

solution: do not turn it off

Wishful thinking.
I had to reboot 4 times today, 3 of them because hildon-desktop hangs under certain circumstances and leaves me no other option if I'm not lucky enough to be on a xterm in that moment. The last time to swap mmc (I boot from mmc) to access it with an external device.

Set up this:
http://www.internettablettalk.com/fo...92&postcount=3

It adds something to the power menu that can at least start up xterm allowing you to restart hildon-desktop if the need to do so arises.

Well, maacruz, you fit into category (a) of my list of people who reboot their tablet frequently ("a hacker/developer who keeps crashing her tablet or needs to boot to another partition"). You are not the norm, and waiting for the tablet to boot is the price you pay for messing about with advanced stuff ;). It's a price I'm willing to pay.

Do not power off your tablet at night to charge it. It is more wasteful of energy. If you "power off" your tablet, then plug it into the wall, the tablet screen lights up again and says "Charging"... The screen, at least on my N800, never turns off!

If you want to charge-and-go, and have a fully charged tablet in the morning, go into "offline" mode, lock your screen and keys, then plug in your charger. The screen will go black, there will be no network activity, and you will have a fully-charged tablet in the morning. It will stay fully-charged, even after unplugging, for many hours in this state. Then, when you want to use the tablet, just hit the unlock key(s), and your screen comes alive, and your tablet is ready to go!

If you are a hacker, and you start a custom set of services that might impact the "idle mode" power consumption, you should make a script that shuts down these services when you want to go into "deep idle".

These tablets have astonishing power-saving capabilities. I ran my tablet as a GPS tracker in the wilderness for three days, with only two sets of 4 AA batteries to charge it at night. I wasted the first set of AA batteries trying to charge my tablet when it was "off". The screen's backlight, on for 8 hours solid while the tablet was supposedly "off", drained the batteries quite effectively. The second set was much more useful, because I charged while the tablet was "on", and the screen was off.

I said 'put the device off, let the device charge'. Not 'let the device charge and then put the power off'. I see the point of offline mode though. I'll try to see how I like it.
