i cant believe that multi touch will be a requirement for MeeGo, It will be targeted for many kinds of devices as i have heard, so a requirement for multi touch would really lock down the number of devices it will support.

If there is something that could be in the way then it is the 2 key things that in my eyes would have been very nice for the N900 to have:

1> double the amount of NAND (rootfs) to 512MB
2> double the amount of RAM to 512MB

I think those 2 thing could potentially be more of a bottleneck for a MeeGo upgrade.
And i think those 2 things where possible for the N900 to have from the start.

Compared to the other feature i would like to see, but that of course didnt make it for the N900 and thats a dual core Cortext A9.... I really need dual core.. it happens to many times that i wait for processes to complete and i see the cpu in the red, so no i dont really need a faster cpu, i just need to have more cores.

Besides the 2 memory things i think the N900 only misses one hardware piece that i also would like to have had and thats a compass. But that will definitely not be MeeGo requirement.... only nice to have.
