If anyone is still wondering why Flash 10.1 isn't already available, and don't want to be bothered to read the rest of this thread, listen up:

Someone has to pay for it. A big license fee to Adobe. Any time you want to have Flash on anything that even smells like a mobile device, Adobe will be cashing in.

My guess is that Adobe is trying to double dip. Nokia paid for a license for v9 on the N900, but Adobe demanded another license for v10.1. The lovely nature of the commercial software business.

Whether Adobe will have a free license for MeeGo ARM Handset (from meego.com) is an important consideration.
