Well if I failed to install Maemo SDK I guess it was as useful to me as Apple SDK at that time. I think this covers all three questions.
What I have read from this forum, I'm not the only one salivating over proper sync support and better graphics hardware.
But I guess I have to give Maemo SDK a second try. If I could develop software for tablet, I might justify 420 euro price tag ( that' $650 ). Too bad they don't sell N800 any more in Finland.
So this means that we can't expect more powerful tablet before next Christmas (maybe spring 2009). Too bad..
