I'm reading this thread all the time head-shacking...

Let's analize a little bit. What do we have?
A official statement from Nokia, on the official Nokia site, that they will drop every software support for the N900? (they can't drop hardware support for at least two years at least in germany).
No!

On the one hand we have a statement from "Nokia" (Who at Nokia? My grandma? The clueless callcenter, acquired by Nokia?) that maemo on the N900 is not upgradeable (whatever that means) posted by a website not giving any details about their source.
How reliable is that?
On the other hand we have the assurance from the meego team, that meego will run on the N900 (in one way or the other).
We know that official Qt 4.6 support is coming to the N900 sooner as some may think (more infos by the end of the month).
So we know that programs made for any platform using Qt will run on the N900.
The N900 is not less usable if there won't come a official meego build.
And the only thing we don't know yet (more infos by the end of the month) is if Nokia will provide their own version of meego for the N900.
Remember: meego is hosted by the Linux foundation. Not Nokia nor Intel.

BTW.: posted from my beloved N900
