the original demo of 10.1 was conducted on, amongst other devices, an N900.
It was the first Device that Adobe pulled out as an example.
At some point, a working version has already been developed to run on the N900 for the public demonstration that was given MONTHS ago.
Since Adobe is quite happy to release beta software, it's a bit rich to turn around and say "you need to follow up 10.1 with Nokia".

Making the (large) assumption that the demo N900 had a full working version of 10.1 (why would you risk a crash on a public display?), how hard would it be for Adobe to allow this version to be downloaded from it's existing sites?
