After the N810 I hoped the N900 would be bigger in stead off smaller, and I don't care that it is a phoe too now. I use the N900, since my N810 died, for writing: poems, opera and musical - and I'm quite used with typing on its keyboard. Nevertheless I wish for a comparable bigger device (I'd love to see the N900 specs with a 5 (with keyboard) - 10 (without) inch maemo tablet.
I also havema SmartQ7 wich I use sometimes for a better overview in written lyrics (bigger screen) and webreading with the chromebrowser. And since it has no flash eather, I understand it is a very cool device!!!
So, yeah, I consider buying a iPad for the bigger screen and smooth interface (that's the downside with the SmartQ, it's interface is more like a desktop than a tablet). I'm also looking at the Entourage Edge, but perhaps it's too big to be portable.
