I can only tell you wait till flash 10.1 will happen here or not.
many ppl saying Flash 10.1 it's only about video, B*****t!

Content is not ready yet but will be and during the device life-time will improve a lot of things more and more useful things will be available with Flash 10.1. And GPU acceleration is not only about video, It's a triangulation of vector drawings processed by GPU as well. Flash 10.1 also means AIR, desktop apps based on AIR run-time with access to the system resources. Future version of flash also will get access to GPS accelerometer mufti-touch gestures etc functionality. Imagine wide range of flash web based apps on it within next 2 years.

If someone is telling me that future version of flash is only youtube, it's just ignorant or get use to his own opinion based on Flash 5 10years ago. Flash with full GPU will be the fastest runtime on the web, faster in many ways. Virtual Machine 2.0 in terms of execution code will be faster than Java when all of graphic task will no longer needs to be done by processor (how many cellphones was based on Java apps for so many years? Is WebOS on Palm Pre based on java? But will get Flash 10.1.. heh) But also in terms of speed of production. Because of graphical nature of Flash it's quite easy and quick to create some useful apps and 3mln army of Flash community just waiting to express themselves.

Keep announcing that we cannot expect Flash 10.1 on powerful black beast INTERNET tablet is like f*****g joke and for this reason I will never recommend this device if you looking for some device for good internet experience. Within next 2 years you going too see more and more blank screens because of lack of Flash 10 support if all that they saying is true. We will end up like IPhone guys, but they have some cool blue lego instead.

So... just wait, I still have a hope myself.

Edit: And see my signature how ironic it is...

EDIT 2:

To prove you how powerfull AS3 is this is a table of speed comparison from 4 years ago. From that time Adobe improved a lot in terms of performance for example added vectors instead of arrays

Here you go http://oddhammer.com/actionscriptperformance/set4/

Bear in mind 4 years ago that was beta AS3 in Flash player 8.5!

Because 70% task in flash are graphic object related and consuming CPU for now this is potential room to speed up this platform and leave more space to do a business logic.
