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.
