Antilles is right, I've never had a problem leaving a tablet or any other Nokia device charging overnight.

Another thing that's good is to never switch off the tablet. Switching the tablet off and on uses a lot of energy, you'll get far more battery life if you just leave it on all the time.

There's an environmental concern that a plugged-in charger may draw a small amount of current even if it's not connected to anything, but that's a separate issue.


All of Nokia's new phone models take microSD cards, so they probably just bought a job-lot of that size. I'm amazed they didn't use microSD on the N810, as it's the only new Nokia product that doesn't.
