Wow, didn't know there is such issue with N900's keyboard, never really happened to me to press these key combinations at once :O Good to know you're aware of them and plan to improve. As well as with magned on the back cover, etc.

I know, I'm still impressed how you found out about the improperly soldered battery for keeping system time on N900 while removing the main battery... On my device it never worked, from the very beginning in 2009.

I know it's a nobrainer, and I'm also puzzled about it missing in GTA04. Full IrDA would be another upgrade for N900 and I would be finally able to let my ancient N95 rest in peace.

My mistake, I forgot about the keyboard leds and counted the main blue/green/yellow/red charging/missed calls/etc led as one, thanks for correcting me.

We take pride in being as open as we can reasonably be, we even select our chips according to their openness, which is sth not that many customers really grok instantly incl all the implications. Back when, we had a hard time accepting the glamo chip's NDAed manuals and gone that route only because there simply was no open GPU available. Same goes for GPU of TI-OMAP. But the device works without using the closed blob 3D-accel libs, so we can ignore our pain in the belly.

I don't think so, but we are inmidst the evaluation process right now. One problem is camera, the GTA04 has only a "crappy" 1.xMP cam. We might not be able to source equivalent to what Nokia used in N900, particularly when it shall be open. We need to see if we can get original N900 cam modules. I guess they must fit into the circuit since they did on N900 ;-)
I wrote "quite" as I didn't really investigate that issue and just saw there are some manuals and schematics I believe it is as open as possible, the "quite" was added only as a precaution in case it would appear somehow closed. And I don't have anything valuable to add to that case either.

Having an open camera would be nice, but having a good quality camera would also be good. Remember we have two cameras in our N900s in fact, so there could be place for both (and the quality of that "crappy" one would be uncomparably better than the one we have now, I'm sure) When you say "open", you mean that not only drivers, but also the schematics are open, right?

Now there's a lot of notes

I'm gonna edit my previous post with information about two cameras in N900 and remove the word "quite" from "quite open manual with schematics" as now I saw them and can say that for my standards they are indeed very open. Thank you for your time to respond
