May be it takes that much time to cold start. But you never do it.
It goes into some kind of suspend after 1-2 minutes and wakes up immediately when you touch the screen. that way it can stay "on" for as much as 10 days without using.
Turning it off and on again consumes 1-2 days worth of power, so there is now point.

It is very much an "always on" device.
If I know I will not be doing anything with my N800 for a while, I put it into SoftPowerOff. The restart is only a couple of seconds, mainly my fumbling with the on/off switch.

One thing that's still bugging me is I had read somewhere on these forums that start up was something like 25-35 seconds. Which surprised me but has me wondering. Is this true? Is this a "cold start" of some sort? is there a way to keep the device active for quicker "warm starts"? Does the battery life prevent the device from sitting in a standby mode for quick access?

25!? days. I have 11 on full charge. How do you get so much battery life out of your ITT?

But battery life is actually up to ~ 1 month if you leave it alone. The ~10 day figure from Nokia's battery applet is quite conservative, unless you have one of the SD cards that slurps juice, or some rogue process eating CPU.

Hi,
I've been here for a while since I've been considering buying a NIT. My biggest hangup has always been that theres no demo units in all of Ontario. So I've never got my hands on one to play with it before I buy it.

Turning it off and on again consumes 1-2 days worth of power, so there is no point.
Over the past year there's been various attempts at reducing the boot time of desktop linux and couple of devs at Intel managed to boot an eeePC (ie. known specific hardware, like our tablets) in 5 seconds.
That said, if the tablet is otherwise considered suitable for one's purposes that 20+ seconds (booting from fast SD card; up to 40+ seconds if one goes overboard with applets running at startup) flies by fairly quickly.

I'm not so sure about the 1 or 2 day thing, depends how the battery applet works out its time remaining, it probably falls off a cliff after the hard work of starting up (the prediction that is) and then recovers when its average calculation realises that average consumption is actually lower.

If the SD card could be a problem:
How could I tell? Would it be enough to umount both of them on my N800? Or would I need to remove them physically? Or is there something in dmesg that shows power consumtion from the SD is too high?
And, of course:
Once I find out it's the SD cards (or one of them), do we have a list of cards known to play nicely with the device and keep the battery alive?

I'm a bit worried about that 25-35 seconds I saw quoted. I'd primarily using my device to pull out and jot quick notes, and having to wait 30 seconds every time I pull it out is a killer. I can just see the time adding up over the 10-25 times I'd use it a day.
