This is a "for wharever it's worth" observation on the power issue. I just received my N800 for Christmas and also two spare Lemar batteries. What I observed was the following. When using the provided Nokia battery and charging it prior to use, I had several occurances of multiple attempts of failing to turn on, but persistant pushing of the on button- 4 to 5 times at most- turned on the N800 and it always booted up sucessfully. So you may ask, so what? Well, here is the interesting rest of the story. When I inserted the Lenmar batteries, from Staples, without charging them first (fortunately they came with a charge) I NEVER saw any start up or shut down issue......NEVER no mattter how many times I went thru the on/off sequence. However, once I charged the batteries in the N800, I USUALLY did see the on/off anomoly. So, I'm thinking and somewhat confirming the comments that there is a rat in either the HW charging circuit or in the OS charing SW that does not properly reset. This may be somewhat redundant to others but from another independent source.

Other than that the N800 is a dream. Connected Igo ultra slim BT keyboard and Anycom BT headset with ease and they both work like a charm. Haven't tried any DVDs, but there is plenty of info on this board on "how to's".
